Resonator  
The RO2073A-5 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 315.05 MHz. This SAW is designed specifically for remote-control and wireless security trans-  
mitters operating in the USA under FCC Part 15, in Canada under DoC RSS-210, and in Italy.
