The RO2125 is a true one-port, surface-acoustic-wave (SAW) resonator in a low-profile TO39 case. It pro-

vides reliable, fundamental-mode, quartz frequency stabilization of local oscillators operating at 304.3 MHz.

This SAW is designed for 315 MHz superhet receivers with 10.7 MHz IF (Philips UAA3201T). Applications

include automotive-keyless-entry receivers operating in the USA under FCC Part 15, in Canada under DoC

RSS-210, and in Italy.
