Resonator
The RO3101C is a true one-port, surface-acoustic-wave (SAW) resonator in a surface-mount ceramic case.
It provides reliable, fundamental-mode, quartz frequency stabilization of fixed-frequency transmitters
operating at 433.92 MHz. This SAW is designed specifically for remote control and wireless security
transmitters operating in Europe under ETSI I-ETS 300 220.
