Abstract
An asymmetric reentrant power coupler suitable for microwave and millimeter bands that includes k input terminals, a plurality of m output terminals, where m is greater than k, and a network coupling the k input terminals to the m output terminals, the network defining n signal paths, where n is greater that m. An input coupler divides an input signal into at least two signal paths. An output coupler recombines a fraction less than one of the divided input signal for propagation to an output terminal. A portion of the non-recombined input signal is propagated to another output terminal. The reentrant coupler may be implemented using Wilkinson, ring, branched line or other coupler types. Couplers that are generally planar as well as coupler that are non-planar are presented.
