The RP1105 is a two-port, 180 degree 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 or near 640 MHz. In the typical CATV converter second LO application, the nominal LO frequency is 639.90 MHz. For these designs, the nominal resonator frequency is higher than the nominal oscillator frequency to allow for production frequency tuning.
