Abstract :
Distributed amplifiers (DAs) using 1mm-gate enhancement-mode AlGaN/GaN HEMT were designed and fabricated. Design process and simulation results of the DA are given. Simulation results show the input and output VSWR (voltage standing wave ratio) of less than 2, associated gain of more than 8.5dB and gain ripple of less than 1dB at frequency from 2GHz to 6GHz.
