Description

The RP1286 is a two-port, 180° surface-acoustic-wave (SAW) resonator in a low-profile TO39 case. RP1286 provides reliable, fundamental-mode, quartz frequency stabilization of fixed-frequency oscillators operating at or near 905.8 MHz. This resonator RP1286 is designed specifically for use in the local oscillator of 916.5 MHz superheterodyne receivers operating in the USA under FCC Part 15.249 and in Canada under DoC RSS-210. It is also suitable for a variety of other oscillator applications.
