摘要

研制了一种用于卫星行波管放大器的ku波段砷化镓线性放大器前置放大器前端。LFE采用混合和伪晶HFET MMIC技术。前端集成了一个可变增益MMIC放大器、两个中功率MMIC放大器和一个功率放大器MMIC。LFE已与短行波管(STWT)集成。测量结果表明，LFE/ twt系统的三阶互调距离提高了10 dB。

Pseudomorphic Ku-band GaAs HFET linearizer preamplifier front end for satellite TWT-amplifiers

A Ku-band GaAs Linearizer Preamplifier Front End (LFE) has been developed for satellite TWT-amplifiers. The LFE is build in hybrid and pseudomorphic HFET MMIC technology. A variable gain MMIC amplifier, two medium power amplifier MMICs, and a power amplifier MMIC are integrated in the Front End. The LFE has been integrated with the short traveling wave tube (STWT). An improvement of 10 dB in the 3rd order intermodulation distance was measured for the LFE/TWT-system.
