TO39-3 Case
Designed for 418.00 MHz 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 RP1237 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 fixed-frequency transmitters operating at
418.0 MHz. The RP1237 is designed specifically for remote-control and wireless security transmitters oper-
ating in the United Kingdom under DTI MPT 1340 and in the USA under FCC Part 15.231 regulations.

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 temperatures
above +65°C. Typically, aging is greatest the first year after manufacture, decreasing significantly in subsequent years.
2.
The frequency fC 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 fTRANSMITTER is less than the resonator fC.
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 manufac-
turer.
5.
Unless noted otherwise, case temperature TC = +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: 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 T
O is 20° less than 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 measured static (nonmotional) capacitance between either pin 1 and ground or pin 2 and ground. The measurement includes case parasitic
capacitance.
