A V-band receiver using a MHMIC multiport circuit is presented in this paper. The millimeterwave frequency conversion is performed using a passive circuit, the multiport, and related power detectors, avoiding the conventional millimeter-wave active costly mixers. Basically, the multiport circuit is an additive mixer in which the resulting sum of millimeter-wave signals is nonlinearly processed using millimeter-wave power detectors. This multiport heterodyne receiver is an excellent candidate for the future low-cost high-speed millimeter-wave wireless communication systems. The operating principle of the proposed heterodyne receiver and demodulation results of high-speed MPSK/QAM signals are presented and discussed in this paper. According to suggested datarate of 100-400 Mbps used to prove the operating principle, the IF of this receiver was chosen at 900 MHz. Therefore, this receiver is a possible alternative solution for WPAN applications
