This component was always

RoHS compliant from the first

date of manufacture.

RO3073A-10

•

Ideal for 315.050 MHz Transmitters

Very Low Series Resistance

Quartz Stability

315.050 MHz

Surface-Mount Ceramic Case

The RO3073A-10 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 315.050 MHz. This SAW is designed for remote-control and wireless security transmitters.

CAUTION: Electrostatic Sensitive Device. Observe precautions for handling.

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 without notice.
