This paper presents a new implementation of a millimeter-wave heterodyne receiver based on six-port technology.The six-port model is implemented in Advanced Design System(ADS) using S-parameter measurements for realistic advanced simulation of a short-range 60 GHz wireless link.Millimeter-wave frequency conversion is performed using a six-port down-converter.The second frequency conversion is performed using conventional means because of low IF.A comparison between the proposed receiver and a conventional balanced millimeter-wave mixer shows that the proposed receiver improves conversion loss and I/Q phase stability over the local oscillator(LO) and RF power ranges.The results of demodulating a V-band quadrature phase-shift keying(QPSK) signal at a high data rate of 100 Mb/s-1 Gb/s are discussed.The results of a bit error rate(BER) and error vector magnitude(EVM) analysis prove that the proposed architecture can be successfully used for wireless link transmission up to 10 m.
