SAW Resonator Specification
16.08.2002
TFR 433M 1/5
Measurement condition
Ambient temperature:
23 °C
Input power level:
10 dBm
Terminating Impedance at fc^*:
for input: 50 Ω || 0 pF
for output: 50 Ω || 0 pF
Characteristics
Remark:
The minimum of the pass band attenuation amin is defined as the insertion loss ae. The centre frequency fc is the frequency of the minimum of
the passband attenuation a_min. The tolerance for the resonant frequency also includes a centre frequency shift due to the temperature coefficient
of frequency TCf in the operating temperature range and a production tolerance for the resonant frequency fR.

*) The terminating impedances depend on parasitics and q-values of matching elements and the board used, and are to be understood as
reference values only. Should there be additional questions, do not hesitate to ask for an application note or contact our design team.
**) Frequency aging is the change in fR with time. Typically aging is greatest first year after manufacture, decreasing in subsequent years.
***) ∆f(Hz) = TCf(ppm/K²) x (T-T₀)² x fTo(MHz)
