摘要
By using 0.15 μm GaAs pHEMT （pseudomorphic high electron mobility transistor） technology,a design of millimeter wave power amplifier microwave monolithic integrated circuit （MMIC） is presented.With careful optimization on circuit structure,this two-stage power amplifier achieves a simulated gain of 15.5 dB with fluctuation of 1 dB from 33 GHz to 37 GHz.A simulated output power of more than 30 dBm in saturation can be drawn from 3 W DC supply with maximum power added efficiency （PAE） of 26%.Rigorous electromagnetic simulation is performed to make sure the simulation results are credible.The whole chip area is 3.99 mm2 including all bond pads.
