Abstract

A Ka-band Gysel power divider based on rectangular waveguide is presented in this paper. The model and equivalent circuit of the presented power divider is introduced. The even- and odd-mode analytical method is applied to analyze the equivalent circuit. A Ka-band waveguide Gysel power divider is designed, optimized, fabricated, and measured. Good agreement between the simulated and measured results is demonstrated. The measured average insertion loss is approximately 0.25 dB from 30 to 34 GHz. The measured output isolation in the same frequency band is greater than 15 dB.
