The RO3115 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 oscillators operating at approximately 417.5 MHz. The RO3115 is designed for IC-based 418 MHz superhet receivers with 500 kHz IF (Philips UAA3201T). Applications include remote-control and wireless security receivers operating in the United Kingdom underDTI MPT 1340 and in the USA under FCC Part 15.
