RO2112

® RO2112 433.42 MHz SAW Resonator Ideal for European 433.92 MHz Superhet Receiver LOs Very Low Series Resistance Quartz Stability Rugged, Hermetic, Low-Profile TO39 Case The RO2112 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 local oscillators operating at approximately 433.42 MHz. The RO2112 is designed for IC based 433.92 MHz superhet receivers with 500 kHz IF (Philips UAA3201T). Applications include remote-control and wireless security devices operating in Europe under ETSI I-ETS 300 220 and in Germany under FTZ 17 TR 2100.
