The RO2102 is a true one-port, surface-acoustic-wave (SAW) resonator in a low-profile TO39 case. It pro-vides reliable, fundamental-mode, quartz frequency stabilization of fixed-frequency oscillators operating at pproximately 393.26 MHz. The RO2102 is designed for 433.92 MHz superhet receivers (with 10.7 MHz IF) in remote-control and wireless security applications operating in Europe under ETSI I-ETS 300 220 and in Germany under FTZ 17 TR 2100.
