Wave digital network of parallel-coupled microstrip based on admittance inverter model

Wave digital network of parallel-coupled microstrip resonator filters is considered in the paper. It is based on equivalent circuit representation by using admittance (J-) inverters and half-wavelength (λ/2) resonators. Wave digital model of admittance inverter (J,-90°), developed here by the use of two-port parallel adaptor network, is described in details. Proposed equivalent network allows for efficient analysis of parallel-coupled microstrip circuits.
