SAW
The RO2216D-6 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 905.800 MHz. This SAW is designed specifically for remote-control and wireless security
transmitters operating in Europe under ETSI I-ETS 300 220 and in Germany under FTZ 17 TR 2100.
