The RS TO39-3 Series of Two-Port SAW Resonators

Electrical Connections

Temperature Characteristics

Either pin 1 or pin 2 may be used for input or output with

these bidirectional, two-port, three-terminal, SAW

resonators. However, impedances and circuit board

parasitics may not be symmetrical, requiring slightly

different oscillator component values for different resonator

connections.

Resonator

The RS1032-1 is a two-port surface-acoustic-wave (SAW) resonator in a low-profile

TO39 case. It provides reliable, fundamental-mode, quartz frequency stabilization of

fixed-frequency oscillators operating at or near 674 MHz. Typical applications include

the second LO in CATV set-top convertors with channel 3 output.

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 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 ± 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: f_C, IL, 3 dB bandwidth, f_Cversus T_C, and C_O.

8. Turnovertemperature, T_O, is the temperature of maximum (or turnover) frequency, f_O. Thenominal frequencyat 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 C_Ois the

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