Abstract :
The operation of a six-port QPSK receiver design is described in this paper. The device consists of two inputs and four outputs. The inputs are the RF and local oscillator (LO) signals while the outputs are the four demodulated QPSK signals. The phase of each individual output signal is located in a different quadrant. The theory for the circuit is described here.
