摘要

A high-power 300 GHz solid-state source chain based on GaN doublers is proposed. The two doublers working at 150 GHz and 300 GHz are designed and fabricated. The pulsed output power exceeds 1000 mW at 148 GHz to 152.5 GHz with an efficiency of 21 % to 29 %. At 151 GHz, a peak pulsed output power of 1322 mW with 27 % efficiency is derived, while a peak efficiency of 33.1 % is determined at 150 GHz ...
