摘要
讨论的对象为采用行波管放大链的宽带微波发射机,阐述了激励功率均衡在发射机设计及调试中的重要作用,指出了激励功率与行波管频率-增益曲线不匹配将会带来的危害,介绍了功率均衡的常用方法。并以某型发射机为例,分析了其均衡方法的不足并提出了改进措施。
The importance of power equalization in design and test of transmitter must be regarded seriously, especially in wide-band microwave transmitter with TWT. The performance of transmitter would be lowered because of the unmatch between in-power and frequency-gain-curve of TWT. Some ways are introduced, the disadvantages of the methods in certain transmitter are analyzed, and some useful suggestions to improve the method are given at the same time.
