  • 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) The RP1308 is a two-port, 180° surface-acoustic-wave (SAW) resonator in a low-profile TO39 case. It pro- vides reliable, fundamental-mode, quartz frequency stabilization of AM, FSK, or PSK transmitters operating at 433.92MHz. 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.

CAUTION: Electrostatic Sensitive Device. Observe precautions for handling. Notes: 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, fOSCILLATOR 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 th e equipment manufac- turer. 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. Pb

One- port resonators can be simulated, as shown, by connecting pins 1 and 2 together. However, for most low-cost consumer products, this is only recommended for retrofit applications and not for new designs.
