前言:本文给出550—650Mc范围内输入100mw,输出20w微带功率放大器的设计,安装及调试。在此频段的微波电子管放大器,体积庞大,需要高压,调谐复杂。采用国产晶体管制成微带宽带功率放大器,体积小,重量轻,功耗低。这样可以用半导体器件代替微波电子管制造L波段中小功率发送设备,使整机得以固体化。本文介绍了放大器设计中应考虑的问题及解决办法。 Preface: This article gives the input 550mW 550mc range of 100mw, output 20w microstrip power amplifier design, installation and commissioning. In this band of microwave tube amplifiers, bulky, high voltage, tuned complex. The use of domestic transistors made of microstrip broadband power amplifier, small size, light weight, low power consumption. This semiconductor devices can be used instead of microwave tubes to manufacture L-band small and medium power transmission equipment, so that the whole machine can be solidified. This article describes the amplifier design should be considered in the problems and solutions.
