131384-HMC1010LP4E

HMC1010LP4E v03.0511 Typical Applications Features The HMC1010LP4E is ideal for: ±1 dB Detection Accuracy to 3.9 GHz • Log –> Root-Mean-Square (RMS) Conversion Input Dynamic Range: -50 dBm to +10 dBm • Received Signal Strength Indication (RSSI) RF Signal Wave shape & Crest Factor Independent • Transmitter Signal Strength Indication (TSSI) Digitally Programmable Integration Bandwidth • RF Power Amplifier Efficiency Control +5V Operation from -40°C to +85°C • Receiver Automatic Gain Control Excellent Temperature Stability • Transmitter Power Control Power-Down Mode 24 Lead 4x4mm SMT Package: 16mm² Functional Diagram General Description The HMC1010LP4E Power Detector is designed for RF power measurement, and control applications for frequencies up to 3.9 GHz. The detector provides an accurate RMS representation of any RF/IF input signal. The output is a temperature compensated monotonic, representation of real signal power, measured with an input sensing range of 60 dB. Power Detectors - SMT 11 RMS POWER DETECTOR DC - 3.9 GHz The HMC1010LP4E is ideally suited to those wide bandwidth, wide dynamic range applications, requiring repeatable measurement of real signal power, especially where RF/IF wave shape and/or crest factor change with time. The integration bandwidth of the HMC1010LP4E is digitally programmable with the use of input pins SCI14 with a range of more than 4 decades. This allows the user to dynamically set the operation bandwidth providing the capability of handling different types of modulations on the same platform. The HMC1010LP4E features an internal OP-AMP at output stage, which provides for slope & intercept adjustments and enables controller application.

A DC bias (Vcc-1.2V) is present on the IN+ and IN- pins, and should not be overridden RMS Output Interface and Transient Response The HMC1010LP4 features digital input pins (SCI1-SCI4) that control the internal integration time constant. Output transient response is determined by the digital integration controls, and output load conditions. Shortest integration time is for SCI=0000, allowed longest integration time is for SCI=1100 (1101, 1110 and 1111 SCI settings are forbidden states). Using larger values of SCI will narrow the operating bandwidth of the integrator, resulting in a longer averaging timeinterval and a more filtered output signal; however 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 times set SCI to 0000. This configuration will operate the integrator at its widest possible bandwidth, resulting in short averaging time-interval and an output signal with little filtering. Most applications will choose a SCI setting that maintains 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. power detectors - SMT 2.8 Table 1: Transient Response vs. SCI Setting[2]: RMSOUT Rise-Time 10% -> 90% (µs) RMSOUT Rise Settling Time (µs)[3] RMSOUT Fall-time 100% -> 10% (µs) Pin = 0 dBm SCI4,3,2,1 Pin = 0 dBm Pin = -20 dBm Pin = -40 dBm Pin = 0 dBm Pin = -20 dBm Pin = -40 dBm Pin = -20 dBm Pin = -40 dBm 0000 0.062 0.038 0.034 0.504 0.546 0.422 1.73 1.73 1.79 0010 0.06 0.045 0.18 0.63 0.63 0.495 5.55 5.55 5.85 0100 0.08 0.06 1.6 2.8 2.65 2.5 22.4 22.3 23.6 0110 1.6 4 7.7 10.5 11 10 93.5 91 96 1000 7 17 31 40 45 45 378 372 386 1010 30 70 138 170 184 182 1510 1510 1590 1100 120 300 580 630 770 780 6400 6400 6600 [1] CW input waveform.

Logslope 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 output. A log-slope of 37.3 mV/dB (@1900 MHz) is set by connecting RMS Output to VSET through resistor network for ß = 1 (see application schematic). The log-slope is adjusted by applying the appropriate resistors on the RMS and VSET pins. Log-intercept is adjusted by applying a DC voltage to the VSET pin. Power Detectors - SMT 11 11 - 21 Optimized slope = ß * log-slope Optimized intercept = log-intercept – (RFBK /RSET) * VBLINE ß= RFBK RFBK // RSHUNT // RSET When RFBK=0 to set RMSOUT=VSET, then ß=1/2 If RSET is not populated, then ß = ½ * (RFBK/ (RFBK // RSHUNT)) and intercept is at nominal value. Example: The logarithmic slope can be simply increased by choosing appropriate RFBK and RSHUNT values while not populating the RSET resistor on the evaluation board to keep the intercept at nominal value. Setting RFBK =4.7KΩ and RSHUNT = 2.2KΩ results in an optimized slope of: Optimized Slope = ß * log_slope = 1.57* 37.3mV / dB Optimized Slope = 58 mV / dB Information furnished by Analog Devices is believed to be accurate and reliable.

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 capacitance (COFS) connected between COFSA, COFSB pins. COFS 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. DC Offset Cancellation Loop ≈ Bandwidth , Hz For example: loop bandwidth for DC cancellation with COFS = 1nF, bandwidth is ~62 kHz Standby Mode The ENX 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 have been chosen, the wake-up time will be lengthened. Modulation Performance – Crest factor performance The HMC1010LP4E can detect modulated signals with very high crest factors accurately. For example, up to 2.7 GHz, a modulated RF signal with a crest factor of 15 dB can be detected with 0.2 dB error. RMSOUT Error vs. Crest Factor over Frequency 1 0.8 RMSOUT ERROR (dB) Power Detectors - SMT 11 0.6 0.4 0.2 0 -0.2 -0.4 900 MHz error from CW (-22 dBm) 1900 MHz error from CW (-22 dBm) 2700 MHz error from CW (-22 dBm) 3900 MHz error from CW (-22 dBm) -0.6 -0.8 -1 3 4 5 6 7 8 9 10 11 12 13 14 15 CREST FACTOR (dB) System Calibration Due to part-to-part variations in log-slope and log-intercept, a system-level calibration is recommended to satisfy absolute accuracy requirements. 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 nonvolatile memory. For example if the following two calibration points were measured at 2.2 GHz: With RMSOUT = 2.321V at Pin= -5 dBm, and RMSOUT = 0.809V at Pin= -45 dBm slope calibration constant = SCC SCC = (-45+5)/(0.809-2.321) = 26.45 dB/V intercept calibration constant = ICC ICC = Pin – SCC*RMSOUT = -5 – 26.45 * 2.321 = -66.39 dBm 11 - 23 Information furnished by Analog Devices is believed to be accurate and reliable.

Layout Considerations • 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 11 Definitions • Log-slope: slope of PIN –> RMSOUT transfer characteristic.
