The RO2101D-1 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 433.935 MHz. This SAW is designed specifically for remote-control and wireless security trans-
mitters operating in Europe under ETSI I-ETS 300 220 and in Germany under FTZ 17 TR 2100.

1.
Frequency aging is the change in fc with time and is specified at +65C or less.
Aging may exceed the specification for prolonged temperatures above +65C.
Typically, aging is greatest the first year after manufacture, decreasing in subse-
quent years, typically <1 ppm/yr (Reference IEEE Transactions on Ultrasonics,
Ferroelectrics, and Frequency Control, Vol. 40, No. 6, November 1993).
2.
The center frequency, fC, is measured at the minimum insertion loss point,
ILMIN, with the resonator in the 50 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.
3.
One or more of the following United States patents apply: 4,454,488 and
4,616,197.
4.
Typically, equipment utilizing this device requires emissions testing and govern-
ment approval, which is the responsibility of the equipment manufacturer.
5.
Unless noted otherwise, case temperature TC = +25°C±2°C.
6.
The design, manufacturing process, and specifications of this device are subject
to change.
7.
Derived mathematically from one or more of the following directly measured
parameters: fC, IL, 3 dB bandwidth, fC versus TC, and CO.
8.
Turnover temperature, TO, is the temperature of maximum (or turnover) fre-
quency, fO. The nominal frequency at any case temperature, TC, may be calcu-
lated from: f= fO [1- FTC (TO -TC)
2]. Typically oscillator T
O is approximately
equal to the specified resonator TO.
9.
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:
CP ≈ CO - 0.05 pF.
