The RO3073A-1 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 315.0 MHz. This SAW is designed specifically for remote control and wireless security  
transmitters.
