The device can be used with input signals having RMS values from -60 dBm to +10 dBm referenced to 50 Ohm and large crest factors with no accuracy degradation. Each RMS detection channel is fully specified for operation up to 3.9 GHz, over a wide dynamic range of 70 dB. The HMC1030LP5E operates from a single +5V supply and provides two linear-in-dB detection outputs at the RMSA and RMSB pins with scaled slopes of 37 mV/dB. The RMSA and RMSB channel outputs provide RMS detection performance in terms of dynamic range, logarithmic linearity and temperature stability similar to Hittite’s HMC1021LP4E RMS Detector. The RMSA and RMSB outputs provide a read of average input signal power, or true-RMS power. Frequency detection up to 3.9 GHz is possible, with excellent channel matching of less than 1 dB, over a wide range of input frequencies and with low temperature drift. The HMC1030LP5E features ETA and ETB pins which provide an accurate voltage output which is linearly proportional to the envelope amplitude of the RF input signal for modulation bandwidths up to 150 MHz. The high bandwidth envelope detection of the HMC1030LP5E makes it ideal for detecting broadband and high crest factor RF signals commonly used in CDMA2000, WCDMA, and LTE systems. Additionally, the instantaneous envelope output can be used to create fast, excessive RF power protection, PA linearization, and efficiency enhancing envelope tracking PA implementations. The HMC1030LP5E includes a buffered PTAT temperature sensor output with a temperature scaling factor of 2 mV/°C yielding a typical output voltage of 567 mV at 0°C. The HMC1030LP5E operates over the -40 to +85°C temperature range, and is available in a compact, 32-lead 5x5 mm leadless QFN package.

These outputs may be used in single-ended or differential configurations. An input voltage applied to the VLVL input pin is used to set the common mode voltage reference level for OUTP and OUTN. On the Hittite evaluation board, the VLVL pin is shorted to VREF2 output to provide a nominal bias voltage of 2.5V; but any external bias voltage may be used to set VLVL.

The HMC1030LP5E’s RMS detector core is designed to measure the actual RMS power of the input signal, independent of the modulated signal waveform complexity or the modulation scheme. The RMS detector core architecture of HMC1030LP5E is composed of a full-wave rectifier, log/antilog circuit, and an integrator as shown above. The RMS output signal is directly proportional to the logarithm of the time-average of VIN2. The bias block also contains temperature compensation circuits which stabilize output accuracy over the entire operating temperature range. The DC offset cancellation circuit actively cancels internal offsets so that even very small input signal levels can be measured accurately. The HMC1030LP5E supports controller mode operation. For more information regarding controller mode operation, please contact Hittite application support. The HMC1030LP5E achieves exceptional RF power measurement accuracy independent of the modulation of the carrier with this system architecture. The relation between the HMC1030LP5E’s RMSOUT output and the RF input power is given below 1 VRMSOUT = ln(ßkG2∫VIN2dt) k VRMSA vs. PIN with WCDMA 4 Carrier @ 1900 MHz 3 Pin = VRMS/[log-slope]+[log-intercept], dBm RMSOUT (V) 2.5 Where ß is op-amp gain set via resistors on the Vset pin.

The extracted envelope information is independent of the average power and the crest factor of the RF signal. The RMS detector core provides a linear-in-dB output of the average RF power, whereas the envelope detector core provides a linear representation of the instantaneous envelope waveform. The envelope detection feature may be used in ultra-fast excessive RF power protection systems, PA linearization techniques and in efficiency enhancing Envelope-Tracking PA implementations.

Simultaneous measurement of instantaneous signal power and average power is essential for taking full advantage of a receive signal chain’s available dynamic range, while avoiding saturation, or to maximize transmitter efficiency. Configuration for the Typical Application The HMC1030LP5E requires a single 5V supply with an adequate power supply decoupling as recommended in the application schematic. Inputs of the HMC1030LP5E are broadband matched to 50 Ohm single-ended with details included in the subsequent “Broadband Single-Ended Input Interface” section. The RMSA & RMSB outputs are typically connected to VSETA & VSETB inputs through a resistive network, resulting in a Pin VRMS transfer characteristic with a slope of 37 mV/dBm (at 1900 MHz) for both channels. However, the RMS outputs can be re-scaled to “magnify” a specific portion of the input sensing range, and to fully utilize the dynamic range of the RMS outputs. Refer to the section under the “Log-Slope and Intercept” section for details. The OUTP & OUTN outputs provide the input signal power ratio between the two power detection channels. The OUTP & OUTN outputs are typically connected to FBKA & FBKB. An input voltage applied to the VLVL input pin is used to set the common mode voltage reference level for the OUTP & OUTN. The VLVL pin is typically connected to VREF2 output to provide a nominal bias voltage of 2.5V. Optionally, external bias voltage may be applied to VLVL. Refer to the section under the “Channel Difference Outputs” for details. The ETA & ETB outputs provide linearly scaled replica of the instantaneous envelope of the modulated RF signal with modulation bandwidths up to 150 MHz for both channels. For optimum performance, the ET outputs of the HMC1030LP5E should be terminated to ground with a 560 Ohm load resistor. Refer to the section under the “Envelope Detector Output” for details. 11 - 27 Information furnished by Analog Devices is believed to be accurate and reliable.

Refer to the section under the “RMS Output Interface and Transient Response” section for details. The COFAP-N & COFBP-N inputs determine the 3dB bandwidth of the input high pass filter for both channels. Typically 1nF external high pass filter capacitors are connected between COFAP & COFAN and between COFBP & COFBN for a banwdith of 62 kHz. The ENX input is the active low enable pin of the whole device. The ENOUT input is the active high enable pin of the integrated OpAmps driving OUTA & OUTB, ETA & ETB. For normal operation, ENX should be connected to GND and ENOUT should be connected to Vcc. Broadband Single-Ended Input Interface The HMC1030LP5E inputs are broadband matched to single-ended 50 Ohm with the configuration shown below. The interface and requires only two external DC blocking capacitors and an external 50 Ohm resistor over the entire frequency band of operation. The integrated broadband single-ended input interface of HMC1030LP5E eliminates the requirement for an external balun transformer or matching network and provides a compact, broadband solution. Note that the provided single-ended input interface covers the whole operating spectrum of the HMC1030LP5E and does not require matching tuning for different frequencies. The performance of the HMC1030LP5E at different frequencies is shown below: 11 POWER DETECTORS - SMT Due to part-to-part variations in log-slope and log-intercept, a system-level calibration is recommended to satisfy absolute accuracy requirements: refer to the “System Calibration” section for more details.

Proprietary design techniques enable extremely good matching between channels over a wide range of input frequencies with low temperature drift. Channel Matching The HMC1030LP5E provides industry leading channel matching performance with the use of proprietary techniques. The channel mismatch is typically less than 100 mV over the specified temperature and frequency range with the integrated broadband single-ended input interface. Channel Matching (RMSA-RMSB) 0.2 0.1 GHz 0.9 GHz 1.9 GHz 2.2 GHz 2.7 GHz 3.5GHz 3.9GHz 0.15 0.1 RMSA-RMSB (V) POWER DETECTORS - SMT 11 Part-to-part variations for single channel RMS detectors complicate simultaneous power readings. Simultaneous signal power measurements are particularly useful for automatic gain/level control and VSWR measurements. When separate power detectors are used, the lack of an accurate match between the power detectors result in measurement errors. Calibration and compensation methods are required to counteract the differences between the separate power detectors. The HMC1030LP5 dual RMS detector greatly simplifies that activity, and will reliably produce more accurate measurements. 0.05 0 -0.05 -0.1 -0.15 -0.2 -70 -60 -50 -40 -30 -20 -10 0 10 INPUT POWER (dBm) Channel Isolation/Interference Off-chip interference between channels should be minimized with good RF board design practices and the quality of the soldered connections. On-chip inter-channel interference, manifests itself as the variation on one detector output due to a relatively strong signal present at the other detector input. Quantitatively, the input-output channel isolation is defined as the difference between the input power levels at both channels when the interfering (higher power level) channel causes a 1 dB measurement error in the victim channel. Worst case channel interference occurs when victim channel has an input signal level just over its detection threshold. Input-Output Channel isolation for HMC1030LP5E is: 55 dB input-output isolation at 0.9 GHz 49 dB input-output isolation up to 2.2 GHz 40 dB input-output isolation up to 3.9 GHz. 11 - 29 Information furnished by Analog Devices is believed to be accurate and reliable.

A slight offset in signal frequency between the two channels can be seen as a ripple at the output of the channel with the lower power level applied at its input. Peaks in the output ripple correspond to the worst-case phase shift for inputoutput interference. The frequency of the output ripple will be equal to the “beat” frequency between the two channels. The magnitude of the output ripple will depend on the SCI (integration) settings and offset capacitors connected to COFA & COFB pins, respectively. The output ripple is reduced by increasing the value of the SCI setting, thereby decreasing the integrator bandwidth. The data was collected using a 1 kHz offset between the channels. 4 0.1 GHz 0.9 GHz 1.9 GHz 2.2 GHz 2.7 GHz 3.5GHz 3.9GHz 3 2 1 0 4 0.1 GHz 0.9 GHz 1.9 GHz 2.2 GHz 2.7 GHz 3.5GHz 3.9GHz 3 2 1 0 -25 -20 -15 -10 -5 0 5 10 -30 -25 -20 INPUT POWER (dBm) -15 -10 -5 0 5 10 INPUT POWER (dBm) Envelope Detector Outputs The HMC1030LP5E features envelope detection for both channels.

ETOUT Response to an RF Input Signal with 100 MHz Modulation Bandwidth POWER DETECTORS - SMT 11 Channel Difference Outputs HMC1030LP5E features OUTP and OUTN “channel difference” outputs that can be used differentially or singleended. The OUTP and OUTN outputs provide direct read of input signal power ratio between the two channels. The OUTP and OUTN are connected to FBKA and FBKB pins respectively. The OUTP and OUTN are defined with the following equations: OUTP = RMSA - RMSB + VLVL OUTN = RMSB - RMSA + VLVL Where, the VLVL is the common mode reference level applied at the VLVL pin. The VLVL pin can be connected to VREF2 output to provide a nominal base voltage of 2.5V. Optionally; external bias voltage can be applied to VLVL. Channel Difference Outputs @ 1900 MHz, Channel A Power Swept, Channel B @ -25 dBm, VLVL=2.5V 4 With the channels of HMC1030LP5E having very low mismatch, and located on the same die, the channel outputs RMSA and RMSB track very closely over temperature.

The RMS output transient response is determined by the digital integration controls, and output load conditions. The SCI3 is the most significant bit, and the longest integration time is for SCI=111. Excessive loading at the RMS output impacts the transient response. It is recommended to keep load resistance above 500 Ohm. For increased load drive capability, consider a buffer amplifier on the RMS output. Using an integrating amplifier on the RMS output allows for an alternative treatment for faster settling times. An external amplifier optimized for transient settling can also provide additional RMS filtering when operating HMC1030LP5E with a lower SCI value.

It will also slow the power detector’s transient response. A larger SCI value favors output accuracy over speed. For the fastest possible transient settling time,s set SCI to 000. This configuration will operate the integrator at its widest possible bandwidth, resulting in short averaging time-interval and an output signal with little filtering. For most applications an SCI setting may be selected to maintain a balance between speed and accuracy. Furthermore, error performance over modulation bandwidth is dependent on the SCI setting. For example modulations with relatively low frequency components and high crest factors may require higher SCI (integration) settings. 0 1 2 3 4 5 6 INTEGRATION SETTING (IN DECIMAL) [1] Measured from 10% to 90% 7 100 10 1 0.1 0 1 2 3 4 5 6 7 INTEGRATION SETTING (IN DECIMAL) [2] Measured from RF switching edge to 1dB (input referred) settling of RMSOUT.

Log-slope and intercept can be adjusted to “magnify” a specific portion of the input sensing range, and to fully utilize the dynamic range of the RMS outputs. A log-slope of 37 mV/dB (@1900 MHz) is set by connecting RMS Output to VSET through a resistor network for B=1 (see application schematic). The log-slope is adjusted by using the appropriate resistors RFBKA, RFBKB, RSHUNTA, RSHUNTB on the RMSA/RMSB and VSETA/VSETB pins. Log-intercept is adjusted by applying DC voltage to the VBLINEA and /VBLINEB. Due to the 15k Ohm input resistance at the VSETA/VSETB pins, moderately low resistance values should be used to minimize the scaling errors. Very low resistor values will reduce the load driving capabilities of RMSA/RMSB outputs while larger values will result in scaling errors and increase of the temperature errors because of the mismatch of the on-chip and external resistor temperature coefficients.

Offset cancellation is a critical function needed for maintenance of measurement accuracy and sensitivity. The DC offset cancellation loop performs this function, and its response is largely defined by the capacitances (COFS) connected between COFPA&COFNA pins and between COFPB&COFNB pins. The COFS capacitors sets the loop bandwidth of the DC offset compensations. Higher COFS values are required for measuring lower RF frequencies. The optimal loop bandwidth setting will allow internal offsets to be cancelled at a minimally acceptable speed. Standby Mode The ENX pin can be used to force the power detector into a low-power standby mode. As ENX is deactivated, power is restored to all of the circuits. There is no memory of previous conditions. Coming out of stand by, internal integration and COFS capacitors will require recharging, so if large SCI values or large COFS capacitor values have been chosen, the wake-up time will be lengthened. Modulation Performance – Crest factor performance The HMC1030LP5E is able to detect the average power of RF signals with complex modulation schemes with exceptional accuracy. The proprietary RMS detection core is optimized to accurately detect the RMS power of the modulated RF signals with very high crest factors. This crest factor immune detection architecture of HMC1030LP5E results in detection accuracy of better than 0.2 dB over the entire operating frequency and temperature range, compared with the CW response under actual WCDMA4TM test signals shown below: Reading Error for WCDMA 4 Carrier wrt CW Response @ +25°C Reading Error for WCDMA 4 Carrier wrt CW Response @ 1900 MHz 1 0.8 0.6 0.6 0.4 0.4 ERROR(dB) 1 0.8 0.2 0 -0.2 100MHz 900MHz 1900MHz 2200MHz 2700MHz 3500MHz 3900MHz -0.4 -0.6 -0.8 -1 -70 -60 -50 -40 -30 -20 INPUT POWER (dBm) 11 - 37 Bandwidth , Hz For example: loop bandwidth for DC cancellation with COFS = 1nF, bandwidth is ~62 kHz ERROR (dB) POWER DETECTORS - SMT 11 1 DC Offset Cancellation Loop ≈ π(500)(COFS + 20 x 1012) 0.2 0 -0.2 -0.4 +25C +85C -40C -0.6 -0.8 -10 0 10 -1 -70 -60 -50 -40 -30 -20 -10 0 10 INPUT POWER (dBm) Information furnished by Analog Devices is believed to be accurate and reliable.

When performing this calibration, choose at least two test points: near the top-end and bottom-end of the measurement range. It is best to measure the calibration points in the regions (of frequency and amplitude) where accuracy is most important. Derive the log-slope and log-intercept, and store them in non-volatile memory. For example if the following two calibration points were measured at 2.35 GHz: With Vrms = 2.34V at Pin = -7 dBm, Now performing a power measurement: and Vrms=1.84V at Pin = -16 dBm Vrms measures 2.13V Slope Calibration Constant = SCC [Measured Pin] = [Measured Vrms]*SCC + ICC SCC = (-16+7)/(1.84-2.34) = 18 dB/V [Measured Pin] = 2.13*18.0 – 49.12 = -10.78 dBm Intercept Calibration Constant = ICC An error of only 0.22 dB ICC = Pin – SCC*Vrms = -7 – 18.0 * 2.34 = -49.12 dBm Factory system calibration measurements should be made using an input signal representative of the application. If the power detector will operate over a wide range of frequencies, choose a central frequency for calibration. Layout Considerations POWER DETECTORS - SMT INPUT SIGNAL CREST FACTOR (dB) • Mount RF input coupling capacitors close to the IN+ and IN- pins. • Solder the heat slug on the package underside to a grounded island which can draw heat away from the die with low thermal impedance. The grounded island should be at RF ground potential. • Connect power detector ground to the RF ground plane, and mount the supply decoupling capacitors close to the supply pins. Definitions: • Log-slope: slope of PIN –> VRMS transfer characteristic. In units of mV/dB • Log-intercept: x-axis intercept of PIN –> VRMS transfer characteristic. In units of dBm. • RMS Output Error: The difference between the measured PIN and actual PIN using a line of best fit. [measured_PIN] = [measured_VRMS] / [best-fit-slope] + [best-fit-intercept], dBm • Input Dynamic Range: the range of average input power for which there is a corresponding RMS output voltage with “RMS Output Error” falling within a specific error tolerance. • Crest Factor: Peak power to average power ratio for time-varying signals.
