Characteristics
Remark:
The reference level for the relative attenuation arel of the TFS 196A is the insertion loss. The insertion loss ae is defined as the insertion loss at the
nominal frequency fN . The centre frequency fC is the arithmetic mean value of the upper and lower frequencies at the 3 dB filter attenuation level relative
to the insertion loss ae. The temperature coefficient of frequency Tc_f is valid both for the reference frequency fc and the frequency response of the filter at
the operating temperature. The frequency shift of the filter at the operating temperature 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.
