Pb
The RO3164E 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 868.35 MHz. This SAW is designed specifically for remote-control and wireless security
transmitters operating under ETSI-ETS 300 220 in Europe and under FTZ 17 TR 2100 in Germany.

Notes:
1. Frequency aging is the change in f_C with time and is specified at +65°C or less.
parameters: f_C, IL, 3 dB bandwidth, f_C versus T_C, and C_O.
Aging may exceed the specification for prolonged temperatures above +65°C.
8. Turnover temperature, T_O, is the temperature of maximum (or turnover)
Typically, aging is greatest the first year after manufacture, decreasing in subse-
quent years.
2. 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
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.

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.

Typically, equipment utilizing this device requires emissions testing and
government approval, which is the responsibility of the equipment manufacturer.

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.
