Wideband Filtering Rat-Race Coupler with Shared Triple-Mode Resonator
In this paper, a filtering rat-race coupler (FRC) is presented, which features the merits of a wideband filtering response, good impedance matching at both input and output ports, good isolation, high-frequency selectivity, small in-band phase difference error, a wide stopband, and small size. It wa...
