2kW短波广播发射机功率合成网络剖析

Analysis on Power Synthesis Network of 2 kW Short Wave Broadcasting Transmitter

随着我国广播信息技术的进步,能够适应复杂地形条件、信号传输距离更远的2 kW短波发射机在广播以及无线信号传输等领域得到越来越广泛的应用。而2 kW短波广播发射机要想实现固态化,必须依赖于功率合成网络。但是传输线变压器由于存在不同的端口接法,其功率合成网络也存在一定的差异,因此需要根据传输线理论来全面分析其平衡电阻和电路原理,对2 kW短波广播发射机功率合成网络进行全面的分析研究。

With the development of broadcasting information technology in China,2kW short wave transmitter,which can adapt to complex terrain conditions and has a longer signal transmission distance,has been widely used in broadcasting and wireless signal transmission.In order to realize the solidification of 2kW short wave broadcasting transmitter,it must rely on the power synthesis network.However,due to the different port connection methods of transmission line transformer,its power synthesis network also has certain differences.Therefore,it is necessary to comprehensively analyze its balanced resistance and circuit principle according to the transmission line theory.In this paper,the power synthesis network of 2kW short wave broadcasting transmitter will be comprehensively analyzed and studied.
