The RO3101E 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 regulations.

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.
