RP1308_15 Datasheet, PDF (1/2 Pages) Murata Manufacturing Co., Ltd. – 433.92 MHz SAW Resonator

• Ideal for 433.92 MHz Low-Power Transmitters
• Nominal Insertion Phase Shift of 180° at Resonance
• Quartz Stability
• Rugged, Hermetic, Low-Profile TO39 Case
• Complies with Directive 2002/95/EC (RoHS) ^Pb
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.

1. Frequency aging is the change in f_C 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 significantly in subsequent years.
2. The frequency f_C is 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_OSCILLATOR or f_TRANSMITTER is 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_C versus 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_O is 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
C_O is the measured static (nonmotional) capacitance between either pin 1 and ground or pin 2 and ground. The measurement includes case parasitic
capacitance.
