•

The RO2112C 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 433.420 MHz. This SAW is designed specifically for remote-control and wireless security transmitters

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