We propose a new four-port BPSK direct conversion receiver based on 0.18 μ m CMOS technology for the first time. The proposed direct conversion receiver is composed of two active combiners, an active balun, two power detectors and a decoder. The designed direct conversion receiver is successfully demonstrated by demodulating BPSK signal with 40 Mbps in the L-band.
