Three-way cascade power divider and combiner for satellite communications

In this paper, a Ka-band in-phase high isolation three-way cascade power divider/combiner for satellite applications is designed, simulated and measured. This three-way power divider/combiner is realized using microstrip line on Printed Circuit Board (PCB) substrate. The average insertion loss is about 5.50 dB over 17.7GHz to 20.7GHz frequency range with a maximum phase difference of 3 degrees.
