RO2113A-1-081398
Ideal for 314.0 MHz Transmitters
Very Low Series Resistance
Quartz Stability
Surface-Mount Ceramic Case with 21 mm2 Footprint
The RO2113A-1 is a one-port, surface-acoustic-wave (SAW) resonator in a surface-mount
ceramic case. It provides reliable, fundamental-mode, quartz frequency stabilization of
local oscillatiors operating at 314 MHz. Applications include automotive keyless entry
receivers operating in the USA under FCC Part 15 and in Canada under DoC RSS-210.

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 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 manufac-
turer.
5.
Unless noted otherwise, case temperature TC = +25°C±2°C.
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) fre-
quency, 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 0.05 pF. Transducer parallel capacitance can
by calculated as: CP ≈ CO - 0.05 pF.
