宽边耦合带线在大功率合成中的应用宽边耦合带线在大功率合成中的应用 段德钦 duandq009@163.com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。关键词:宽边耦合带状线 功率合成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.Keyword: Broadside-Coupled Strip Transmission Lines Power Synthesis150MHz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,设计冗余大,稳定可靠,性价比较好。 以下是介绍……
