FIELD: surface acoustic wave systems. SUBSTANCE: temperature-compensated piezocrystal has at least one flat surface. Crystal element is composed of GaPO<SB>4</SB> and its flat surface is determined by Euler angles lambda in 0 deg. region, ?? between 40 and 75 deg. (better between 50 and 60 deg.), and theta in 0 deg. region. EFFECT: improved thermal stability. 8 cl, 3 dwg
