RO2118A General Description
The RO2118A 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 318 MHz. This SAW is designed for AM transmitters remote control and wireless security applications operating in the USA under FCC Part 15, in Canada under DoC RSS-210, and in Italy.
