SURFACE ACOUSTIC WAVE RESONATOR USING REFLECTORS AS HEATING ELEMENTS Russian patent published in 2013 - IPC H03H9/25 

FIELD: radio engineering, communication.

SUBSTANCE: surface acoustic wave resonator using reflectors as heating elements has one or more interdigital transducers and surface acoustic wave reflectors made from short-circuited metal strips, wherein the heating element used is short-circuited reflectors that are partitioned to increase direct current resistance with one or more partitions per reflector.

EFFECT: shorter time for tuning the resonator to operating frequency, eliminating temperature gradient between the heater and the resonator, reducing power consumption and simplifying the design of the thermostabilised resonator while preserving its initial dimensions without the heater.
