315.00 MHz

SAW

The RO3073A-11 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 315.00 MHz. This SAW is designed for remote control and wireless security transmitters.

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) fre-

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

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

quent years.

quency, f_O. The nominal frequency at any case temperature, T_C, may be calcu-

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

lated from: f = f_O[1 - FTC (T_O-T_C)²]. Typically oscillator T_Ois approximately

equal to the specified resonator T_O.

This equivalent RLC model approximates resonator performance near the reso-

nant frequency and is provided for reference only. The capacitance C_Ois the

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

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

capacitance with "NC” pads unconnected. Case parasitic capacitance is approx-

imately 0.05 pF. Transducer parallel capacitance can by calculated as:

C_P≈ C_O- 0.05 pF.

with the resonator in the 50 Ω test system (VSWR ≤ 1.2:1). The shunt induc-

tance, L_TEST, is tuned for parallel resonance with C_Oat f_C. Typically, f_OSCILLA-

_TORor 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 govern-

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

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

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

to change without notice.
