The RO3103 is a true one-port, surface-acoustic-wave (SAW) resonator in a low-profile TO39 case. It
provides reliable, fundamental-mode, quartz frequency stabilization of fixed-frequency transmitters operating
at 418.0 MHz. The RO2103 is designed specifically for remote-control and wireless security transmitters
operating in the United Kingdom under dTI MPT 1340 and in the USA under FCC Part 15.

Frequency aging is the change in f C with time and is specified at +65°C or
less. Aging may exceed the specification for prolonged temperatures
above +65°C. Typically, aging is greatest the first year after manufacture,
decreasing significantly 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 O at f C .
Typically, f OSCILLATOR or f TRANSMITTER is less than the resonator f C .
One or more of the following United States patents apply: 4,454,488 and
4,616,197 and others pending.
Typically, equipment designs utilizing this device require emissions testing
and government approval, which is the responsibility of the equipment
manufacturer.
Unless noted otherwise, case temperature T C = +25°C±2°C.

subject to change without notice.
Derived mathematically from one or more of the following directly
measured parameters: f C , IL, 3 dB bandwidth, f C versus 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 O is 20°C
less than 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 pin1 and pin 2 measured
at low frequency (10 MHz) with a capacitance meter. The measurement
includes case parasitic capacitance with a floating case. For usual
grounded case applications (with ground connected to either pin 1 or pin 2
and to the case), add approximately 0.25 pF to C O .
