A compact multiple‐way double ring‐cavity power divider

Abstract

AbstractDesign of an ultra‐wideband multiple‐way power divider based on the coaxial ring cavity configuration is presented. The proposed design includes increased numbers of the power divider ports, compared to the available designs, thanks to an incorporated coaxial power divider. For this purpose, the cavity layer in the ring cavity power divider is designed in two separate cavity rings and each ring is fed independently through an integrated coaxial power divider. Therefore, the number of the output ports is increased by 50%. A sample prototype is simulated for ultra wideband frequency range, and the performance is computed by using a full wave electromagnetic simulation technique. The power divider has 50 ports of 32 outer ring and 18 inner ring ports. The impedance bandwidth for the return loss <15 dB is obtained for the frequency range of 4‐10.5 GHz. The average insertion loss, amplitude imbalance, phase imbalance, and group delay are better than 0.4 dB, ±0.8 dB, 12°, and 0.6 ns, respectively.
