The RO2164A 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 operat-

ing at 868.35 MHz. This SAW is designed specifically for remote-control and wireless security transmitters

operating under ETSI-ETS 300 220 in Europe and under FTZ 17 TR 2100 in Germany.
