摘　　要：本文利用微波平面结构谐振模式情况下场等效的方法,对单扇形微带传输线电路进行了分析,并在此基础上介绍了一种宽带直流偏置电路的分析和设计方法。此种形式的偏置电路应用于一种C波段的微波放大器上,仿真和实验结果证明了这种宽带直流偏置电路是有效的。In this paper, the analysis of the microstrip radial-line stubs is presented. The method is based on the electromagnetic field expansion in terms of resonant modes of the planar structure. Using this theory, the analysis and design of a kind of broad-band dc bias circuit is presented. The bias circuit is used in a C-Band microwave amplifier. Simulation and testing result prove that the bias circuit is good.
