A 60 GHz multi-port heterodyne receiver (MPHR) with rapid analog carrier recovery circuit is presented in this paper. The millimeter-wave frequency conversion is performed using a passive circuit, the multi-port interferometer, and related power detectors, avoiding the conventional millimeter-wave active costly mixers. The operating principle of MPHR and the demodulation results of 500 Mb/s QPSK signal are presented and discussed in this paper. This receiver is an excellent candidate for the future low-cost, ultra wideband, short range, millimeter-wave wireless personal area networks.
