The RP1094 is a two-port, 180 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 915 MHz. This resonator is designed specifically for use in low-power transmitters operating in the USA under FCC Part 15.249 regulations. It is also suitable for a variety of other oscillator applications.
