Abstract :
A four-way waveguide power divider/combiner has been developed using a radial waveguide. The divider has an insertion loss of less than 0.5 dB and a power balance of +or-0.2 dB over a bandwidth of 2.5 GHz at X-band. A power combiner using this circuit and four Gunn oscillators has been demonstrated with over 70% combining efficiency. The circuit should have applications in millimeter-wave power combining and high-power microwave systems.<>
