The RO2101 is a true one-port, surface-acoustic-wave (SAW) resonator in a low-profile TO39 case. It pro-

vides reliable, fundamental-mode, quartz frequency stabilization of fixed-frequency transmitters operating at

433.92 MHz. The RO2101 is designed specifically for remote-control and wireless security transmitters oper-

ating in Europe under ETSI I-ETS 300 220 and in Germany under FTZ 17 TR 2100.
