A New Carrier Recovery Method for a Six-port Millimeter Wave Receiver
نویسندگان
چکیده
-A new direct conversion wide band (23 GHz – 31 GHz) six-port millimetre wave receiver for QPSK communications suitable for integrated circuit fabrication is proposed, to satisfy mass-market wireless communications. The receiver contains one multi-chip module consisting of a wide-band six-port junction, four RF detectors (diodes), video amplifiers and I&Q decoder. The prototype circuits are fabricated in hybrid integrated circuits and the receiver topology is suitable for fabrication in microwave monolithic integrated circuits (MMICs). A new method of carrier recovery using six-port output voltages is proposed. A control signal for VCO is generated and simulation results are presented.
