Resonator  
The RO3116A 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 fixed-frequency transmitters  
operating at 303.325 MHz. This SAW is designed specifically for AM transmitters in wireless security and  
remote control applications operating in the USA under FCC Part 15, in Australia, in Japan, and in Korea.
