Abstract
A 50-ohm 100-2200 MHz distributed power amplifier (DPA) MMIC has been developed using Nitronexpsilas proprietary GaN-on-Si NRF1 process. The DPA MMIC exhibits -10dB minimum input/output return loss, 39.4 dBm average output power, and a power added efficiencies of 30 to 66% over the entire bandwidth.
