Abstract
In this paper, we suggest a new 4-port receiver instead of 6-port schematic for the demodulation of BPSK. The designed receiver is implemented by a ring-hybrid balun, two power detectors, and a comparator For the validity of the proposed receiver, we demonstrate a BPSK modulator/demodulator at 2.45 GHz. The measured data shows that the proposed 4-port receiver can successfully demodulate a data rate of 1 Mbps.
