RO2123A 307.3 MHz SAW Resonator Ideal for 318 MHz Superhet Receiver LOs Very Low Series Resistance Quartz Stability Surface-Mount, Ceramic Case with 21 mm2 Footprint Complies with Directive 2002/95/EC (RoHS) The RO2123A is a true one-port, surface-acoustic-wave (SAW) resonator in a surface-mount, ceramic case. It provides reliable, fundamental-mode, quartz frequency stabilization of local oscillators operating at approximately 307.3 MHz. This SAW is designed for 318 MHz superhet receivers with 10.7 MHz IF. Applications include remote-control and wireless security receivers operating in the USA under FCC Part 15, in Canada under DoC RSS-210, and in Australia.
