GENERAL DESCRIPTION
The ADL5570 is a high linearity 2.3 GHz to 2.4 GHz power amplifier designed for WiMAX 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 26 dBm while maintaining an EVM of ≤3% with a supply voltage of 3.5V. PAE is greater than 20% at POUT = 25 dBm with a 3.5V supply voltage.
