摘要

本文介绍了一种用于VSAT ODU(室外机)应用的ku波段1瓦AlGaAs/InGaAs/GaAs PHEMT MMIC功率放大器。这款四级放大器设计为完全匹配50欧姆的输入和输出阻抗。在7 V、700 mA直流偏置条件下，该放大器在14 ~ 17 GHz频段实现了30 dB小信号增益、30.8 dBm 1-dB增益压缩功率和24.5%的功率附加效率(PAE)，以及31.3 dBm饱和功率和27.5%的PAE。

A four-stage Ku-band 1 watt PHEMT MMIC power amplifier

In this paper, a Ku-band 1 watt AlGaAs/InGaAs/GaAs PHEMT MMIC power amplifier for VSAT ODU (outdoor unit) applications is demonstrated. This four-stage amplifier is designed to fully match for a 50 ohm input and output impedance. With 7 V and 700 mA DC bias condition, the amplifier has achieved 30 dB small-signal gain, 30.8 dBm 1-dB gain compression power with 24.5% power-added efficiency (PAE) and 31.3 dBm saturation power with 27.5% PAE from 14 to 17 GHz.
