The RO2116A 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 303.325 MHz. This SAW is designed for 303.325 MHz superhet receivers with 500 kHz IF (Philips UAA3201T). Applications inlude remote-control and wireless security receivers operating in the USA under FCC Part 15, in Japan, in Australia, and in Korea.
