Abstract
The interfering resonances of transverse modes are moade to occur far from the fundamental resonant frequency in a surface acoustic wave (SAW) resonator by connecting a plurality of SAW sub-devices in parallel. The frequency response of this parallel combination is essentially undistorted. Interfering spurious resonances caused by the transverse modes become inconsequential. These devices have a substantially higher power handling capability as compared to conventional resonators with comparable Q. This capability reduces the phase noise of oscillators stabilized by these resonators.
