Abstract

Rectangular waveguide to circular waveguide mode converter is a critical components of a high-power microwave test system. In certain frequency band, the traditional method of round - rectangular waveguide mode converter can´t satisfy the performance requirements. In order to solve this problem, this paper puts forward a kind of compact structure, and it has the characteristic of small reflection coefficient, wide bandwidth, waveform conversion efficiency high. Its center frequency is 16 GHz, the bandwidth of 8 GHz. Its relative bandwidth is 50%, and VSWR is less than 1.1 in 12G-20G, and insertion loss is greater than -0.02.
