Abstract:
An eight-way waveguide-based power combiner/divider is presented and investigated in the frequency range 7.5-10.5 GHz. A simple approach is proposed for design purposes. The measured combiner shows a good agreement between the simulated and measured results. Insertion loss is about -0.3 dB, return loss is less than -15 dB and isolation between adjacent output ports is better than -11 dB at 8.5 GHz and reaches about -14 dB at 9.5 GHz.
