The RO2116 is a true one-port, surface-acoustic-wave (SAW) resonator in a low-profile TO39 case. It provides reliable, fundamental-mode, quartz frequency stabilization of local oscillators operating at approximately 303.325 MHz. The RO2116 is designed for IC-based 303.825 MHz superhet receivers with 500 kHz IF (Philips UAA3201T). Applications include wireless remote-control and security receivers operating in the USA under FCC Part 15, in Japan, in Australia, and in Korea.
