摘要
为了提高基于微带的微波功率合成电路在X波段以上的带宽及合成效率,对Wilkinson功分器进行了改进,从而提出了一种新型能够工作在X波段频率的Wilkinson功分器。在此基础上,结合双Schiffman正交移相器和MMIC芯片实现了一种Ku波段功率放大器,在13~16 GHz的饱和功率大于1 W,小信号增益大于20 dB,合成效率大于80%。
In order to inhance the band width and composing efficiency of a micro-strip power composer circuit above X band,the Wilkinson＇s power divider has been improved and a new type Wilkinson＇s power divider,which is able to work well above X band,is obtained.Combining it with Schiffman orthogonal shifters and MMIC power amplifiers,a Ku band power composer is realized,demonstrating 1 W of saturated power,above 20 dB of gain and 80 % of composing efficiency within 13~16 GHz.
