摘要

The design of an 18.8 GHz to 20.2 GHz GaAs PHEMT Doherty amplifier is described. Tested performance of this amplifier is presented including single tone performance and NPR performance with a broadband waveform. The broadband waveform is a digitally generated, 500 MHz, noise like signal. This broadband 500 MHz NPR test is described and is a new capability setup for testing broadband communication power amplifiers.
