LOW VELOCITY ZERO TEMPERATURE COEFFICIENT ACOUSTIC SURFACE WAVE DELAY LINE HAVING GROUP AND PHASE VELOCITY VECTOR COINCIDENCE

摘要

An acoustic surface wave delay line having a single crystal tellurium dioxide substrate member the acoustic surface wave propagation surface of which substantially coincides with a plane defined by the Euler angles Lambda = 0 DEG , Mu = 58.2 DEG , and Theta = 0 DEG .
