The design of a 48-way high power capacity sectorial waveguide power divider

Abstract

A 48-way high power capacity (HPC) sectorial waveguide power divider in X band is designed. The design approach and simple analysis of the power divider are discussed. The simulated results demonstrate that the maximum magnitude difference among all outputs is 0.8 dB, and the maximum phase difference is 9°. The 20 dB return loss bandwidth is 900 MHz from 8.9 GHz to 9.8 GHz. The power handling capability of the divider reaches 2.7 GW in vacuum state. The proposed power divider has the advantages of simple fabrication, low insertion-loss and high power capacity.
