  Abstract

In this paper, waveguide-based power combiner using conventional slotline-to-microstrip transition was proposed at Ka-band The proposed 2-way and 4-way power combiner consist of waveguide-to-slotline transition, two or four slotline to microstrip transitions, and impedance matching networks. Their structures were simulated and optimized by 3-D FEM simulation- The 2-way power combiner showed a very low back-lo-back insertion loss of 1.0 dB and return loss better than l5 dB from 25.7 GHz to 29.8 GHz except the resonant frequency The 2-way power combining approach was extended Io 4-way power combining using slotline tee junction. The 4-way power combiner showed the similar performance to that of 2-way power combiner with 2 GHz smaller bandwidth.
