Abstract :
A novel 2-4 PSK differential demodulator based on a three-port SAW delay line is described. A method for optimising the performance by tuning the carrier frequency using the DC output of the demodulator is outlined. The optimum performance of the demodulator was within 0.4 dB of theory for a bit error ratio of 10-3.
