Description

The RP1308 is a two-port, 180 surface-acoustic-wave (SAW) resonator in a low-profile TO39 case. RP1308 providesreliable, fundamental-mode, quartz frequency stabilization of local oscillators operating at approximately423.22 MHz. The RP1308 is designed for 433.92 MHz superhet receivers in remote-control andwireless security applications operating in Europe under ETSI I-ETS 300 220 and in Germany under FTZ 17TR 2100.
