摘要: A phase shifter includes a transformer connected between first port and second including coil that is magnetically coupled to the coil, parasitic inductance component; an impedance adjustment circuit reactance element suppresses deviation in due component of transformer. coupling coefficient value are determined such phase-shift amount changes accordance with frequency band.
