摘要
This invention, being the fundamental bodily waves filter which uses harmonic mode HBAR, includes two HBAR resonators (20 and 22) which become from transducer (8) and the substrate (12) which are joined appropriately by the electric acoustic wave respectively, it regards the fundamental bodily waves filter. The element (28) in order to join the first vibrator (20), with the second vibrator (22) and the ebanetsusento wave, in order to oppose, as it is laid out, includes the identical one somatotype acoustic substrate (12) which is joined with piezoelectric transducer (8) with the wave which possesses the mode of vibration of identical shearing or length with the identical reference electrode (10).
