SAW
The RO3104E 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 operating in the USA under FCC Part 15, in Australia, in Japan, and in Korea.

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 Ω 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°C±2°C.

subject to change.
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.
