The couplers are basically power dividers/ combiners with equal or unequal power division and with or without phase shift. Branch line couplers [1, 2], power dividers [3-7] and hybrid ring couplers [8, 9] are the some of the power dividing/ combining devices. The rat-race coupler is one of basic building blocks used in RF and microwave circuits.Single balanced mixers can remove either the LO or RF content from the IF output without the use of filters by using two diodes and a 180° hybrid coupler as a balun. Early wideband receivers used a 90° hybrid combiner, which separated the RF and LO, but the isolation was dependent on how well the diodes were impedance matched.Rat-race hybrid design: The proposed VS phase inverter is implemented on the rat-race hybrid. Fig. 4 showsthe layout and the fab-ricated hybrid with the angle, θ, of 90° and radius, R, of 10 mm used in the VS phase inverter.

180 hybrid ring couplers (also called rat race couplers) are four-port devices used to either equally split an input signal or to sum two combined signals. An additional benefit of the hybrid ring is to alternately provide equally-split but 180 degree phase-shifted output signals. The center conductor ring is 1 wavelengths in circumference (or ...The hybrid-ring directional coupler described in this paper allows a larger power-split ratio for the same impedance lines, and thereby increases the range of the power-split ratio that can be ...
