SAW
The RO3104A 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 303.825 MHz. This SAW is designed specifically for AM transmitters in wireless security and
remote control applications.

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 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 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 ± 2 °C.

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
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.
Tape and Reel standard per ANSI / EIA 481.
