The ACTQ964/868.3/QCC8C is a two-port, 180° surface-acoustic-wave (SAW) resonator in a
surface-mount ceramic QCC8C case. It provides reliable, fundamental-mode, quartz frequency
stabilization i.e. in transmitters or local oscillators operating at 868.300 MHz.

The frequency fC is the frequency of minimum IL with the resonator in the specified test fixture in a 50 Ω test
system with VSWR≤1.2:1.
Unless noted otherwise, case temperature T C = +25°C±2°C.
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.
Turnover temperature, T0, is the temperature of maximum (or turnover) frequency, f 0. The nominal frequency at
2
any case temperature, TC, may be calculated from: f = f 0 [1 - FTC (T 0 - TC) ].
This equivalent RLC model approximates resonator performance near the resonant frequency and is provided
for reference only. The capacitance C 0 is the measured static (non-motional) capacitance between input terminal
and ground or output terminal and ground. The measurement includes case parasitic capacitance.
Derived mathematically from one or more of the following directly measured parameters: f C, IL, 3 dB bandwidth,
fC versus TC, and C0.
The specifications of this device are based on the test circuit shown above and subject to change or
obsolescence without notice.
Typically, equipment utilizing this device requires emissions testing and government approval, which is the
responsibility of the equipment manufacturer.
Our liability is only assumed for the Surface Acoustic Wave (SAW) component(s) per se, not for applications,
processes and circuits implemented within components or assemblies.
In keeping with our ongoing policy of product evolvement and improvement, the above specification is subject to change without notice.
