Divider/combiner with enhanced isolation and reflection cancellation

Abstract

An advanced power divider/combiner concept is presented and demonstrated. The new concept provides significant isolation and enhanced reflection cancelation for 1:N dividers/combiners. It is demonstrated with a 1:4, 2-8 GHz, with 0.4 dB insertion loss, 20 dB isolation, and 10 dB return loss improvement over conventional (e.g. Wilkinson) dividers. Additionally, a 1:3, 4-12 GHz (100% bandwidth) divider with low insertion loss, high isolation and high return loss improvement is demonstrated.
