Abstract :
An FM modulator/demodulator system employing three identical surface transverse wave (STW) resonators is described. It operates at a centre frequency of 1012 MHz and can transmit data at over 100 kbit/s. This low cost system has a low noise and can detect FM signals with a deviation of less than 0.1 ppm.
