Designed for 312 MHz Low-Power Superhet Transmitters Nominal Insertion Phase Shift 180° at Resonance Quartz Stability Rugged, Hermetic, Low-Profile TO39 Case
The 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 fixed-frequency transmitters operating at 312 MHz. Typical applications include wireless security and remote-control receivers operating in the USA under FCC Part 15 and in Canada under DoC RSS-210.

1. Frequency aging is the change in fC with time and is specified +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 subsequent years. 2. The frequency C is the frequency of minimum IL with the resonator in the specified test fixture a 50 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: 4,616,197. 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 2°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: [1 - FTC (TO - TC)2]. Typically, oscillator 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.by RF Monolithics, Inc.

The curve shown on the right accounts for resonator contribution only and does not include LC component temperature contributions.
The plot shown below is a typical frequency response for the RP series of two-port resonators. The plot is for RP1094.
This SAW resonator can be used in oscillator or transmitter designs that require 180° phase shift at resonance in a two-port configuration. Oneport 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.
