Characteristics
Remark:
The reference level for the relative attenuation arel of TFS 111B is the minimum of the pass band attenuation amin. This value is defined as the
insertion loss ae. The centre frequency fc is the arithmetic mean value of the upper and lower frequencies at the 20,0 dB filter attenuation level
relative to the insertion loss ae.

*) 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.
