This PA incorporates ANADIGICS’ HELP4TM technology to deliver exceptional efficiency at low power levels and low quiescent current without the need for external voltage regulators or converters. The device is manufactured using advanced InGaPPlus TM HBT technology offering state-of-the-art reliability, temperature stability, and ruggedness. Three selectable bias modes that optimize efficiency for different output power levels and a shutdown mode with low leakage current increase handset talk and standby time. A “daisy chainable” directional coupler is integrated in the module, thus eliminating the need of an external coupler. The self-contained 3 mm x 3 mm x 1 mm surface mount package incorporates matching networks optimized for output power, efficiency, and linearity in a 50 Ω system.

The Bias Control table below lists the recommended modes of operation for various applications. Shutdown Mode The power amplifier may be placed in a shutdown mode by applying logic low levels (see Operating Ranges table) to the VEN, VMODE1 and VMODE2 voltages. Three operating modes are recommended to optimize current consumption. High Bias/High Power operating mode is for POUT levels > 16 dBm. At ~16 dBm - 6 dBm, the PA could be switched to Medium Power Mode. For POUT levels < ~6 dBm, the PA could be switched to Low Power Mode for extremely low current consumption. Bias Modes The power amplifier may be placed in either Low, Medium or High Bias modes by applying the appropriate logic level (see Operating Ranges table) Table 5: Bias Control APPLICATION POUT LEVELS BIAS MODE VEN VMODE1 VMODE2 Low power (Low Bias Mode) < +6 dBm Low +1.8 V +1.8 V +1.8 V 3.1 - 4.35 V ≥ 3.1 V Med power (Medium Bias Mode) > 6 dBm < +16 dBm Low +1.8 V +1.8 V 0V 3.1 - 4.35 V ≥ 3.1 V High power (High Bias Mode) > +16 dBm High +1.8 V 0V 0V 3.1 - 4.35 V ≥ 3.1 V - Shutdown 0V 0V 0V 3.1 - 4.35 V ≥ 3.1 V Shutdown VCC VBATT VCC C6 2.2 µF C1 18 pF GND at slug 1 2 RFIN VMODE2 VMODE1 VEN (1) VBATT VCC RFIN RFOUT 10 3 VMODE2 CPLIN 8 4 VMODE1 GND 7 5 VEN CPLOUT 6 Notes: (1) Rise and Fall time on VEN Control Signal must be ≤ 1.0 µS.
