  • DUAL-BAND 360 DEGREE PHASE SHIFTER USING SERIES/PARALLEL RESONANCE CIRCUIT FOR PHASED ARRAY ANTENNA SYSTEM
    Publication number: 20230216468
    Abstract: Disclosed is a dual-band phase shifter in which series/parallel resonance circuits are applied to a polyphase filter to implement a phase shifter, which is a core block of a multi-channel RFIC for implementing a phased array antenna system. The dual-band phase shifter may be configured by converting a capacitor (C) of an LC circuit or a CL circuit in the RFIC into a series resonance circuit and converting an inductor (L) thereof into a parallel resonance circuit, so that a signal generator operating in one frequency band can operate in a dual-band.
