DATA SHEET SKY77324: iPAC™ PAM for Quad-Band GSM / GPRS Applications • Quad-band cellular handsets encompassing - Class 4 GSM850/900 - Class 1 DCS1800 PCS1900 - Class 12 GPRS multi-slot operation The SKY77324 Power Amplifier Module (PAM) is designed in a low profile (1.2 mm), compact form factor for quad-band cellular handsets comprising GSM850/900, DCS1800, and PCS1900 operation. The PAM also supports Class 12 General Packet Radio Service (GPRS) multi-slot operation. The module consists of separate GSM850/900 PA and DCS1800/PCS1900 PA blocks, impedance-matching circuitry for 50 Ω input and output impedances, and a Power Amplifier Control (PAC) block with an internal current-sense resistor. The custom CMOS integrated circuit provides the internal PAC function and interface circuitry. Fabricated onto a single Gallium Arsenide (GaAs) die, one Heterojunction Bipolar Transistor (HBT) PA block supports the GSM850/900 bands and the other supports the DCS1800 and PCS1900 bands. Both PA blocks share common power supply pins to distribute current. The GaAs die, the Silicon (Si) die, and the passive components are mounted on a multi-layer laminate substrate. The assembly is encapsulated with plastic overmold. RF input and output ports of the SKY77324 are internally matched to a 50 Ω load to reduce the number of external components for a quad-band design. Extremely low leakage current (2.5 µA, typical) of the dual PA module maximizes handset standby time. The SKY77324 also contains band-select switching circuitry to select GSM (logic 0) or DCS/PCS (logic 1) as determined from the Band Select (BS) signal. In Figure 1, below, the BS pin selects the PA output (DCS/PCS OUT or GSM850/900 OUT) and the Analog Power Control (VAPC) controls the level of output power. VBATT and VSENSE pins connect to an internal current-sense resistor and interface to an integrated power amplifier control (iPAC™) function, which is insensitive to variations in temperature, power supply, and process. The PAC ENABLE input allows initial turn-on of PAC circuitry to minimize battery drain.

This device has an Open Loop mode that allows bypassing of the internal PAC circuitry. See the Technical Information section at end of this document for further information.

Figure 7 lists the Electrostatic Discharge (ESD) immunity level for each pin of the SKY77324 module. The numbers specify the ESD threshold levels for each pin where the I-V curve between the pin and ground starts to show degradation. ESD testing was performed in compliance with MIL-STD-883E Method 3015.7 using the Human Body Model. If the magnitude of ESD damage threshold is found to consistently exceed 2000 volts, this so is indicated. If the ESD damage threshold below 2000 volts is measured for either polarity, numbers are indicated that represent worst case values observed in product characterization. Figure 7. ESD Sensitivity Areas (Top View) Various failure criteria can be utilized when performing ESD testing. Many vendors employ relaxed ESD failure standards, which fail devices only after “the pin fails the electrical specification limits” or “the pin becomes completely nonfunctional”. Skyworks’ most stringent criteria fail devices as soon as the pin begins to show any degradation on a curve tracer. To avoid ESD damage, both latent and visible, it is very important that the product assembly and test areas follow the Class-1 ESD handling precautions listed in Table 5. Table 5.

The PA collector current will then be directly proportional to the VAPC input voltage over the range of 400 mV to 2.1 V. To meet the GSM power versus time mask and switching transient requirements the PAM must be provided with a DAC ramp profile on the VAPC input as well as proper timing on digital controls for the PAC circuitry. Note: Please refer to 3GPP TS 51.010-1: Mobile Station (MS) conformance specification. All GSM specifications are now the responsibility of 3GPP. The standards are available at http://www.3GPP.org. burst power that results from the ramp profile delivered by the DAC to the VAPC input. The transmit power must not exceed the given limits at the time specified relative to the start and end of the data burst. Additional requirements are placed on spectral components generated by switching transients. Ramping at high rates will result in components that violate these spectral limits. A ramp control signal must be applied to the VAPC pin, which results in the desired power ramp response. The log relationship of VAPC to POUT, along with the finite bandwidth and potential slew rate limitations of the feedback loop, results in a complex mapping of the ramp profile to the actual output power. Careful attention is required in generating the input waveform which results in the desired output response. Figure 9 shows an example of the Skyworks PAM test setup for evaluation of RF performance with various ramp profiles. The user’s test setup may also include a TX/RX switch and a diplexer in the output signal path. Alternatively, the SKY77324 PAM may be installed in a phone board. Figure 10 shows an example Skyworks software interface for the setup in Figure 9 that can be used to create a recommended DAC ramp profile. This profile is loaded from the computer into the Skyworks emulator board during test. The software also handles the required PAC Enable and TX_RX control signal timing. Figure 11 and Figure 12 show the GSM and DCS/PCS calibration screens, respectively, called up from the ramp profile interface in Figure 10. These calibrations, done for each PAM, generate an output power versus VAPC curve from sample data. Points from this curve are combined with the ramp coefficients to generate the DAC ramp during handset operation or test. The SKY77324 has been designed to comply with interface requirements and DAC resolution of leading base band devices. The ramp profile typically consists of a pedestal voltage, 10–16 discrete voltage steps on the rising edge of the burst, a constant region, 10–16 steps on the falling edge, and a final voltage. Typically, the user defines the start, stop, and 10–16 percentage values for each rising and falling edge, which are then applied as discrete voltages at the VAPC input. For the SKY77324, generally the same profile, scaled in amplitude, is used for all frequencies and power control levels. The ultimate purpose is to keep the RF output power ramp within the time mask and to maintain acceptable spectral limits at specified offset frequencies. The VAPC input has an internal reconstruction filter such that external resistors or capacitors are unnecessary on the phone board or the test fixture.

Example of DCS/PCS Calibration Screen Open Loop Control Mode With PAC ENABLE at a logic low, the voltage applied to VAPC is buffered and applied directly to the bases of the RF devices. This mode of operation provides backward compatibility with the existing amplifier designs and allows for various test scenarios. As with previous designs, an active clamp acts as a protection mechanism limiting the maximum voltage that can be applied to the base of the RF devices. This clamp voltage decreases with increasing supply voltage. The enable threshold on the VAPC input for open loop operation exhibits a wide tolerance, which may vary from 200 mV to 800 mV. When enabled in Open Loop mode, the internal PAC circuitry (V-I converter and integrator) is placed in standby.
