SAW
The RO3101A-11 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 433.92 MHz. This SAW is designed specifically for remote-control and wireless security
transmitters operating in Europe under ETSI I-ETS 300 220-1.

Notes:
1. 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
subject to change without notice.
7. Derived mathematically from one or more of the following directly
above +65 °C. Typically, aging is greatest the first year after manufacture,
measured parameters: f_C, IL, 3 dB bandwidth, f_C versus T_C, and C_O.
decreasing in subsequent years.
8. Turnover temperature, T_O, is the temperature of maximum (or turnover)
2. The center frequency, f_C, is measured at the minimum insertion loss point,
frequency, f_O. The nominal frequency at any case temperature, T_C, may be
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
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.
9. This equivalent RLC model approximates resonator performance near the
resonator f_C.

4. Typically, equipment utilizing this device requires emissions testing and
measured at low frequency (10 MHz) with a capacitance meter. The
measurement includes parasitic capacitance with "NC” pads unconnected.

manufacturer.
5. Unless noted otherwise, case temperature T_C = +25 ± 2 °C.
6. The design, manufacturing process, and specifications of this device are
Case parasitic capacitance is approximately 0.05 pF. Transducer parallel
capacitance can by calculated as: C_P ≈ C_O - 0.05 pF.
