Characteristics
Remark:
reference level for the relative attenuation arel of the TFS166 is the minimum of the pass band attenuation amin. The minimum of the pass band attenuation
amin is defined as the insertion loss ae. The centre frequency fc is the arithmetic mean value of the upper and lower frequencies at the 2 dB filter attenuation
level relative to the insertion loss ae. The temperature coefficient of frequency Tcf is valid for both the reference frequency fc and the frequency response of
the filter in the operating temperature range. The frequency shift of the filter in the operating temperature range is not included in the production tolerance
scheme.

*) 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.
**) ∆f(Hz) = TCf(ppm/K) x (T-T0) x fcat(MHz).
