Abstract :
We propose a new four-port BPSK direct conversion receiver based on 0.18 ??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.
