Hybrid Bulk Acoustic Wave Structure for Temperature Stability in LTE Applications

A novel structure of hybrid bulk acoustic wave (BAW) resonator with low temperature coefficient of frequency (TCF) is presented. Implemented with a pair of quarter-wave reflectors on air-cavity reflector, the hybrid BAW resonator exhibits a TCF of as low as -11.5 ppm/°C and an effective electro-mech...
