SAW Resonator

The RO3104D-1 is a true one-port, surface-acoustic-wave (SAW) resonator in a surface-mount, ceramic

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

operating at 303.825 MHz. This SAW is designed specifically for AM transmitters in wireless security and

remote control applications operating in the USA under FCC Part 15, in Australia, in Japan, and in Korea.

Notes:

Frequency aging is the change in f_Cwith time and is specified at +65°C or less.

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.

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_Ois

approximately equal to the specified resonator T_O.

Aging may exceed the specification for prolonged temperatures above +65°C.

Typically, aging is greatest the first year after manufacture, decreasing in

subsequent years.

The center frequency, f_C, is measured at the minimum insertion loss point, IL_MIN

with the resonator in the 50  test system (VSWR  1.2:1). The shunt

inductance, L_TEST, is tuned for parallel resonance with C_Oat f_C. Typically,

This equivalent RLC model approximates resonator performance near the

resonant frequency and is provided for reference only. The capacitance C_Ois

f_OSCILLATORor f_TRANSMITTERis approximately equal to the resonator f_C.

One or more of the following United States patents apply: 4,454,488 and

4,616,197.

Typically, equipment utilizing this device requires emissions testing and

government approval, which is the responsibility of the equipment manufacturer.

Unless noted otherwise, case temperature T_C= +25°C±2°C.

the static (nonmotional) capacitance between the two terminals measured at low

frequency (10 MHz) with a capacitance meter. The measurement includes

parasitic capacitance with "NC” pads unconnected. Case parasitic capacitance

is approximately 0.05 pF. Transducer parallel capacitance can by calculated as:

C_P C_O- 0.05 pF.

The design, manufacturing process, and specifications of this device are subject

to change.
