Abstract :
A 1010 bit, biphase-coded, surface-wave matched filter on s.t.-cut quartz is described, and waveforms are shown. The matched filter was designed to operate with a 60 MHz carrier and 10 Mbit/s code rate (0.1 ¿s tap spacing). Measurements indicate that the predicted performance is achievable by application of straightforward design procedures and fabrication techniques.
