GENERAL DESCRIPTION

The ADL5570 is a high linearity 2.3 GHz to 2.4 GHz power amplifier designed for WiMAX terminals using TDD operation at a duty cycle of 31. With a gain of 29 dB and an output compression point of 31 dBm at 2.35 GHz, it can operate at an output power level up to 26 dBm while maintaining an EVM of ≤3 (OFDM 16 or 64 QAM) with a supply voltage of 3.5 V. PAE is 20 @ POUT = 25 dBm.
