摘要 介绍了鳍线魔T的性质及设计原则,对其中的激励问题提出了一种近似计算方法,给出了适合于电路工程的设计经验公式,利用鳍线魔 T 结构在 Ka 波段实现了平衡混频器。混频器包括中放在内的 DSB 噪声系数小于6.8dB,最小值6.0dB,工作带宽2.0GHz,本振射频隔离大于20 dB。 The properties and the design method of finline magic tee are described.Theapproximate calculation on the exciting problem and the design empiric formula of finline magictee for cicuit engineering are presented.The finline balanced mixer is realized in Ka band byusing the magic tee structure.The mixer with an IF amplifier has a DSB noise figure of lessthan 6.8dB and 6.0dB in minimum,an operating bandwidth of 2GHz and an isolation ofgreater than 20dB.
