RO2023-10 Datasheet, PDF (1/2 Pages) RF Monolithics, Inc – 433.97 MH SAW Resonator
®
• Ideal for European 433.92 MHz Transmitters
• Low Series Resistance
• Quartz Stability
• Rugged, Hermetic, Low-Profile TO39 Case
• Complies with Directive 2002/95/EC (RoHS) Pb
The RO2023-10 is a true one-port, surface-acoustic-wave (SAW) resonator in a low-profile TO39 case. It pro-
vides reliable, fundamental-mode, quartz frequency stabilization of fixed-frequency transmitters operating at
433.92 MHz. The RO2023-10 is designed specifically for remote-control and wireless security devices oper-
ating 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 +65°C or less.
Aging may exceed the specification for prolonged temperatures above +65°C.
Typically, aging is greatest the first year after manufacture, decreasing in sub-
sequent 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.
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 gov-
ernment 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 sub-
ject 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) 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 TO is 20°C less than
the specified resonator TO.
9. This equivalent RLC model approximates resonator performance near the res-
onant frequency and is provided for reference only. The capacitance CO is the
static (nonmotional) capacitance between Pin1 and Pin 2 measured at low fre-
quency (10 MHz) with a capacitance meter. The measurement includes case
parasitic capacitance with a floating case. For usual grounded case applica-
tions (with grund connected to either Pin 1 or Pin 2 and to the case), add
approximately 0.25 pF to CO.
