The ADL5571 is a high linearity 2.5 GHz to 2.7 GHz power amplifier designed for WiMAX mobile terminals and CPEs using TDD operation at a duty cycle of 50% or lower. With a gain of 29 dB and an output compression point of 31 dBm, it can operate at an output power level up to 27 dBm while maintaining an EVM of 3% with a supply voltage of 5 V. PAE is 21% at POUT = 25 dBm with a 3.3 V supply voltage. The ADL5571 RF input is matched to provide an input return loss of better than 10 dB. The open-collector output is externally matched with a microstrip line and an external shunt capacitor. The ADL5571 operates over a supply voltage range from 3.2 V to 5 V with a current of 450 mA burst rms when delivering 25 dBm (3.3 V supply). A standby mode is available that reduces the quiescent current to 9 mA, which is useful when a TDD terminal is receiving data.
