A Study of Group-Type Single-Phase Unidirectional Saw Transducers on LiNb03 and Quartz.
Abstract
This Memorandum describes a development of the SPUDT (Single Phase Undirectional Transducer) concept. The fabrication of such devices requires a single stage of photolithography. Prototype devices have shown very encouraging passband characteristics with an insertion loss of less than 3 dB on LiNb03 at 100 MHz, and less than 6 dB on quartz at 400 MHz. In each case the amplitude response is essentially ripple-free, and the phase characteristic agreeable linear. (Great Britain)
