Abstract

A broadband MMIC power amplifier operating from 17 to 36 GHz is developed for point-to-multipoint applications using 0.25 /spl mu/m AlGaAs/InGaAs/GaAs pseudomorphic high electron mobility transistor (PHEMT). The amplifier is fully monolithic, with all matching, biasing, and DC block circuitry included on the chip. Operated under 5 V power supply, the two-stage balanced power amplifier has 11 dB small-signal gain with a 3 dB bandwidth from 17 to 36 GHz. The output powers at 1 dB compression are 20 dBm at 26 and 28 GHz and greater than 23 dBm at 30.5 GHz.

17-36 GHz宽带PHEMT MMIC功率放大器，用于点对多点应用

采用0.25 /spl mu/m AlGaAs/InGaAs/GaAs伪晶高电子迁移率晶体管(PHEMT)，开发了一种工作频率为17至36 GHz的宽带MMIC功率放大器，用于点对多点应用。放大器是完全单片的，所有匹配、偏置和直流模块电路都包含在芯片上。两级平衡功率放大器在5v电源下工作，具有11db小信号增益和3db带宽，范围为17至36ghz。1db压缩时的输出功率在26ghz和28ghz时为20dbm，在30.5 GHz时大于23dbm。
