Rat-Race Couplers. Rat-race couplers are hybrid couplers with a coupling factor of 3 dB. They are manufactured using microstrips in the shape of a ring or circle. The three branches of a rat-race coupler are 90° phase shifted from each other, and the other branch is 270° phase-shifted. A microstrip hybrid ring coupler providing the same function as a convental magic Tee in waveguide or a coaxial rat-race. The ring is comprised of four equal electrical length arcs between the input-output ports. The 180° phase shift is introduced in one of the four ring arcs by a tightly coupled parallel strip conductor which extends towards the interior of the ring and has an electrical ...A new wide band 180° hybrid coupler is proposed in microstrip line structure, which is easy to fabricate and suitable for microwave integrated circuits (MICs) and monolithic microwave integrated circuits (MMICs). The hybrid consists of a Wilkinson power splitter and a short circuit stub 180° differential phase shifter. Due to the simplicity of structure, this circuit is easy to implement at ...
