The RO2164A 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 operat-
ing 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.

Frequency aging is the change in fC with time and is specified at +65°C or less.
to change without notice.
Derived mathematically from one or more of the following directly measured
parameters: fC, IL, 3 dB bandwidth, fC versus TC, and CO.
Turnover temperature, TO, is the temperature of maximum (or turnover) fre-
quency, fO. The nominal frequency at any case temperature, TC, may be calcu-

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.
The center frequency, fC, is measured at the minimum insertion loss point,
ILMIN, with the resonator in the 50 W test system (VSWR £ 1.2:1). The shunt
inductance, LTEST, is tuned for parallel resonance with CO at fC. Typically, fOS-
CILLATOR or fTRANSMITTER is approximately equal to the resonator fC.
One or more of the following United States patents apply: 4,454,488 and

Typically, equipment utilizing this device requires emissions testing and govern-
ment approval, which is the responsibility of the equipment manufacturer.
Unless noted otherwise, case temperature TC = +25°C±2°C.
lated from: f = fO [1 - FTC (TO -TC)2]. Typically oscillator TO is approximately
equal to the specified resonator TO.
This equivalent RLC model approximates resonator performance near the reso-
nant frequency and is provided for reference only. The capacitance CO is the
static (nonmotional) capacitance between the two terminals measured at low
frequency (10 MHz) with a capacitance meter. The measurement includes para-
sitic capacitance with "NC” pads unconnected. Case parasitic capacitance is
approximately 0.05 pF. Transducer parallel capacitance can by calculated as:
