Twin Ferrite Toroidal Phase Shifter in Back-Ridged Waveguide

本文导出双环背脊波导锁式铁氧体移相器的传播常数公式。在典型参数下,计算了该器件的差相移和插入损耗。结果表明,该移相器的优值和差相移比同一条件下的矩形波导的同类移相器的大。为了验证文中所给方程的正确性,对差相移作了实验,其结果与计算值基本相符。

In this paper,propagation constant formula for twin ferrite toroidal phase shifter using Back-Ridged waveguide is given.With typical parameters,the differential phase shift and the insertion loss are calculated.The results show that the figure of merit and the differential phase shift of the phase shifter are larger than these of rectangular waveguide phase shifter under the same condition.To prove the equation given in the paper,differential phase shift is measured by experiment.The results are basically agreement with those calculated by given equation
