Characteristics
Remark:
The reference level for the relative attenuation arel of the TFS 146 is the minimum of the pass band attenuation. This value is defined as the insertion loss
ae. The nominal frequency fN is fixed at 146,5 MHz without any tolerance. The values of relative attenuation arel are guaranteed for the whole operating
temperature range. The frequency shift of the filter in the operating temperature range is 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.
**) ∆fc(Hz) = Tc_f(ppm/K) x (T - T_o) x f_CAT (MHz).
******) The ripple is defined as a difference in the characteristic to a fixed golden sample. It is additionally allowed to remove cubic trends from the
differential characteristic in case of these ripple measurements
