A simple V-band radio IQ receiver architecture based around a six-port monolithic microwave integrated circuit (MMIC) is presented. The receiver assembly is designed to cover the 57-65 GHz broadband wireless communication system frequency allocation. The receiver that has an integral 10 dB microstrip antenna consumes 120 mW of dc power and occupies an area of 23 mm x 16 mm. The receiver can be used in heterodyne or in homodyne mode and has the capacity to demodulate quadrature amplitude modulation (QAM), binary phase shift keying (BPSK)/quadrature phase shift keying (QPSK)/offset quadrature phase shift keying (OQPSK). At 60 GHz the receiver can operate over 10 m range for transmitter effective isotropic radiated power (EIRP) of 20 dBm.
