The RO2073A-5 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 315.05 MHz. This SAW is designed specifically for remote-control and wireless security
transmitters operating in the USA under FCC Part 15, in Canada under DoC RSS-210, and in Italy.

CAUTION: Electrostatic Sensitive Device. Observe precautions for handling.
Notes:
1.
Lifetime (10 year) frequency aging.
2.
The center frequency, fC, is measured at the minimum insertion loss point, ILMIN, with the resonator in the 50 Ω test system (VSWR ≤ 1.2:1). The
shunt inductance, LTEST, is tuned for parallel resonance with CO at fC.
3.
One or more of the following United States patents apply: 4,454,488 and 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 TC = +25°C±2°C for all specifications.
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: fC, IL, 3 dB bandwidth, fC versus TC, and CO.
8.
Turnover temperature, TO, is the temperature of maximum (or turnover) frequency, fO. The nominal frequency at any case temperature, TC, may be
calculated from: f = fO [1 - FTC (TO -TC)
2].
9.
This equivalent RLC model approximates resonator performance near the resonant frequency and is provided for reference only. The capacitance
CO 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 0.05pF. Transducer parallel
capacitance can be calculated as: CP ≈ CO -0.05 pF.
