摘要:宽边耦合带状线在VHF频段大功率合成中,用作合成器和分配器,具有插入损耗小
、两端口相位和幅值均衡度好、功率容量大、体积小、便于装配和调试的特点,是
一种很好的大功率合成方式。

Abstract: Using Broadside-Coupled Strip Transmission Lines as synthesizer
and dispatcher in high-powered VHF synthesis, there are several
advantages such as less insertion loss; better amplitude and phase
balance between two port; higher power capacity; compactness;
convenient for installation and adjustment. It is a valuable synthesis
method.

150MHz频段无线寻呼发射机通常发射功率为100W,工作电压为13.8VDC。单管在该电压条
件下,能达100W者甚少,国内外寻呼发射机生产厂家多数都采用双管合成的方式,单管
功率可达75W,合成后仅使用至100W,设计冗……
