| Abstract(in English) | Branch-line quadrature hybrids are widely used for various microwave applications such as antenna feed networks, power amplifiers, and mixers. We propose a quadrature hybrid with multiple spurious suppressions provided by resonance circuits at junctions of the hybrid. Design equations for the lumped-element hybrid and the distributed-line hybrid are derived with matching conditions at the fundamental frequency and resonant conditions at the spurious frequencies. The availability of the proposed quadrature hybrids has been verified by simulations. |
