The RO3164E 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 868.35 MHz. This SAW is designed specifically for remote-control and wireless security

transmitters operating under ETSI-ETS 300 220 in Europe and under FTZ 17 TR 2100 in Germany.

CAUTION: Electrostatic Sensitive Device. Observe precautions for handling.

Notes:

1.

Aging may exceed the specification for prolonged temperatures above +65°C.

Typically, aging is greatest the first year after manufacture, decreasing in subse-

quent years.

This equivalent RLC model approximates resonator performance near the

the static (nonmotional) capacitance between the two terminals measured at low

frequency (10 MHz) with a capacitance meter. The measurement includes

parasitic capacitance with "NC” pads unconnected. Case parasitic capacitance

is approximately 0.05 pF. Transducer parallel capacitance can by calculated as:
