RoHS Compliance

This component is compliant

with RoHS directive.

This component was always

RoHS compliant from the first

date of manufacture.

RO3073E-14

• Ideal for 315 MHz Automotive-Keyless-Entry Transmitters

• Very Low Series Resistance

• Quartz Stability

315.00 MHz

SAW Resonator

The RO3073E-14 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 approximately 315.00 MHz. This SAW is designed for automotive keyless-entry applications

operating in the USA under FCC Part 15, in Canada under IC RSS-210, and in Italy.

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

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.

This equivalent RLC model approximates resonator performance near the

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

is 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.

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.

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, 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.

10. Tape and Reel Standard Per ANSI / EIA 481.

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

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

subject to change without notice.
