THERMALLY STABLE NARROW-BAND SURFACE ACOUSTIC WAVE FILTER |
摘要 |
FIELD: physics, acoustics.SUBSTANCE: invention relates to acoustoelectronics and can be used in making thermally stable surface acoustic wave filters. The thermally stable narrow-band surface acoustic wave filter comprises an acoustic line - a piezoelectric substrate with interdigital transducers formed on its surface; on the reverse side the substrate there is a flat metal or dielectric plate with through-holes on edges of the plate, through which the plate is mounted to the acoustic line and simultaneously to the mounting support of the housing using a rubber-like adhesive with a high coefficient of linear thermal expansion; the plate is mounted in the central part to the acoustic line by a thin layer of a rubber-like adhesive with a high coefficient of linear thermal expansion; between the mounting support of the housing and the plate there is a gap which is greater than the sag of the mounting support of the housing at subzero and above-zero ambient temperatures.EFFECT: high thermal stability and improved mechanical strength of the structure.5 dwg |
