Generalized equations are presented for the design of a rat-race coupler with a phase inverter and an arbitrary power division, where its four arms are built by symmetric reciprocal lossless two-port networks. According to these equations, uniform- and stepped-impedance rat-race couplers are analyzed and synthesized with dual-band arbitrary power divisions. The relationships between the geometries...
Dual-band rat-race couplers are implemented with double-sided parallel-strip line to provide arbitrary power divisions. Both the uniform-impedance and stepped-impedance cases are explored, and design equations are derived for the two cases. With our method, the rat-race coupler can be quickly developed to satisfy the design specifications. By using phase inverter, arms with arbitrary electrical lengths...
