Murata's SAR series of surface acoustic wave (SAW) resonators are provided in an industry-standard 3.0 x 3.0 x 1.15mm SMD package. Available frequencies include the popular 315.00 and 433.92MHz frequencies, as well as many others. Use of a SAW resonator at these frequencies can avoid the complicated and more costly frequency-multiplying circuits typically required with quartz crystal resonators. SAW Resonators utilize mechanical vibration of piezoelectric material, while LC/RC utilizes electrical resonance. Oscillators using a SAW Resonator are stable against peripheral circuit or supply voltage fluctuation, providing freedom from adjustment.
