Description

The RO2103 is a true one-port, surface-acoustic-wave (SAW) resonator in a low-profile TO39 case. It provides
reliable, fundamental-mode, quartz frequency stabilization of fixed-frequency transmitters operating at 418.0 MHz. The RO2103 is designed specifically for remote-control and wireless security transmitters operating in the United Kingdom under dTI MPT 1340 and in the USA under FCC Part 15.
