The RO2112A-17 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 local oscillators operating at
approximately 433.42 MHz. This SAW is designed for 433.92 MHz superhet receivers with 500 kHz IF
(Philips UAA3201T). Applications include remote-control and wireless security receivers operating in Europe
under ETSI I-ETS 300 220 and in Germany under FTZ 17 TR 2100.

Notes:
1.
Frequency aging is the change in fC with time and is specified at
+65°C or less. Aging may exceed the specification for prolonged tem-
peratures above +65°C. Typically, aging is greatest the first year after
manufacture, decreasing in subsequent years.
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. Typically, fOSCILLATOR 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 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].
Typically, oscillator TO is approximately equal to the specified
resonator TO.
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 “NC”
pads unconnected. Case parasitic capacitance is approximately
0.05 pF. Transducer parallel capacitance can be calculated as: CP ≈
CO - 0.05 pF.
