UHF　300W功率合成链

UHF 300W power combining chain

介绍一种ＵＨＦ ３００Ｗ功率合成链，分析组成该功率合成链的三种不同的功率合成网络，这三种网络分别为同相功分器合成网络。９０°正交功率合成网络和反相推挽功率合成网络。采用该功率合成链设计的固态功放组件，在分米波波段获得３００Ｗ的线性输出功率，该组件在国产的彩色电视发射机中有良好的应用前景。

This paper introduces a UHF 300Wpower combining chain, and analysis three different Power combining networks consisting of the combining chain, i.e., in-phase power combining network, 90° orthognal Power combining network and phase-inverted push-pull power combining network.The solid state power amplifier module designed using this power combining chain provides 300W linear power output in decimeter wave band. This module has bright prospects for its applications in color TV transmitters to be manufactured in China.
