RP1308

•

Ideal for 433.92 MHz Low-Power Transmitters

Nominal Insertion Phase Shift of 180° at Resonance

Quartz Stability

433.92 MHz

SAW Resonator

Rugged, Hermetic, Low-Profile TO39 Case

Complies with Directive 2002/95/EC (RoHS)

The RP1308 is a two-port, 180° surface-acoustic-wave (SAW) resonator in a low-profile TO39

case. It provides reliable, fundamental-mode, quartz frequency stabilization of AM, FSK, or PSK

transmitters operating at 433.92 MHz. The RP1308 was designed specifically for remote-control

and wireless security transmitters 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 f_Cwith 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 significantly in subsequent years.

2. The frequency f_Cis the frequency of minimum IL with the resonator in the specified test fixture in a 50 Ω test system with VSWR ≤ 1.2:1. Typically,

f_OSCILLATORor f_TRANSMITTERis less than the resonator f_C.

3. One or more of the following United States patents apply: 4,454,488; 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 T_C= +25°C± 5°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: f_C, IL, 3 dB bandwidth, f_Cversus T_C, and C_O.

8. Turnover temperature, T_O, is the temperature of maximum (or turnover) frequency, f_O. The nominal frequency at any case temperature, T_C, may be

calculated from: f = f_O[1 - FTC (T_O- T_C)²]. Typically, oscillator T_Ois 20° less than the specified resonator T_O.

9. This equivalent RLC model approximates resonator performance near the resonant frequency and is provided for reference only. The capacitance

_Ois the measured static (nonmotional) capacitance between either pin 1 and ground or pin 2 and ground. The measurement includes case parasitic

capacitance.
