A novel W-band solid-state power divider/combiner network based on waveguide microstrip structure

A novel W-band solid-state power divider/combiner network is proposed, using a compact waveguide configuration of magic tee and waveguide-to-microstrip transition. The novel magic tee is improved by using an inverted T added into the double-T junction. The measured isolation of the novel magic tee between two output ports is better than 13.5dB. The measured return loss of divider/combiner network is better than 15dB from 92GHz to 96GHz frequency range.
