The RO3164E-3 is a one-port surface-acoustic-wave (SAW) resonator packaged in a surface-mount ceramic
case. It provides reliable, fundamental-mode quartz frequency stabilization of fixed-frequency transmitters
operating at 868.35 MHz. This SAW is designed specifically for remote-control and wireless security
transmitters operating under ETSI EN 300 220-2.
