The RO3113 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 oscillators operating at approximately 314.5 MHz. The RO3113 is designed for IC based 315 MHz superhet receivers using a 500 kHz IF (Philips UAA3201T). Applications include wireless remote-control and security devices operating in the USA under FCC Part 15 and in Canada under DoC RSS-210.
