Abstract :
Results are given of radiation resistance measurements made on 30 electrode pair interdigital transducers deposited on crystalline quartz for the purpose of generating acoustic Rayleigh waves. On the basis of these data, a delay line has been designed exhibiting the following characteristics: minimum insertion loss 9.8 dB, delay 9.6 µs, -3 dB bandwidth 3.5 MHz, input impedance 50 Ω at center frequency of 96.8 MHz, isolation 90 dB, spurious echo rejection > 20 dB.
