Abstract

A four-way all-metal-waveguide power divider has been presented and analyzed in this paper. A metal matching cylinder and a transition waveguide are applied to implement wide impedance matching from the input port to the four output ports. A simple equivalent-circuit model for this power-dividing structure has been developed. Moreover, the theoretical power-handling capability of the presented power-dividing structure has also been investigated. To verify the validity of the proposed structure, a four-way power divider at W-band has been fabricated with conventional machining. The measured return loss is greater than 14.5 dB from 82 GHz to 107 GHz. The measured insertion loss of the four-way all-metal-waveguide power divider is about 6.5 dB, which corresponds to a power-combining efficiency of 89 %.
