The RO2102a-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 oscillators operating
at 423.22 MHz. The RO2102A-1 is designed specifically for the LO of 433.92 MHz superhet receivers in
remote-control and wireless security applications operating under ETSI I-ETS 300 220 in Europe.

Notes:
otes:
1.
Lifetime (10 year frequency aging.
2.
The center frequency, fC, is measured at the minimum insertion loss
point, ILMIN, with the resonator in the 50 Ω test system (VSWR ≤
1.2:1). The shunt inductance, LTEST, is tuned for parallel resonance
with CO at 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 government 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 without notice.
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) frequency, fO. The nominal frequency at any case
temperature, TC, may be calculated from: f = fO [1 - FTC (TO -TC)
2].
9.
This equivalent RLC model approximates resonator performance near
the resonant 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 parasitic capacitance with a floating
case. For usual grounded case applications (with ground connected
to either pin 1 or pin 2 and to the case), add approximately 0.25 pF to
CO.
