The RP1298 is a two-port, 180° surface-acoustic-wave (SAW) resonator in a low-profile TO39 case. RP1298 provides reliable, fundamental-mode, quartz frequency stabilization of local oscillators operating at approximately 423.22 MHz. The RP1298 is designed for 433.92 MHz superhet receivers in remote-control and wireless security applications operating in Europe under ETSI I-ETS 300 220 and in Germany under FTZ 17 TR 2100.
