Characteristics
Remark:
The reference level for the relative attenuation arel of the TFS 70AT 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 nominal frequency fN is fixed at 70 MHz. The values for relative attenuation are guaranteed at
ambient temperature. The frequency shift of the filter over temperature defined by the temperature coefficient of frequency Tc_f 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.
