LAMB WAVE LOOP CIRCUIT FOR ACOUSTIC WAVE FILTER

摘要

Aspects of this disclosure relate to Lamb wave elements and acoustic wave resonators. Certain embodiments relate to an acoustic wave filter and a loop circuit that includes and Lamb wave and is configured to generate an anti-phase signal to a target signal at a particular frequency. Some embodiments relate to an acoustic wave assembly that includes a bulk acoustic wave resonator and a Lamb wave element implemented on a common substrate. Various embodiments relate to acoustic wave filters that include a Lamb wave resonator and a second acoustic wave resonator that is a different type of acoustic wave resonator than the Lamb wave resonator.
