Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 190 C 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 190,0 MHz without tolerance.
The values of the pass band ripple and the relative attenuation arel are guaranteed in the whole operating temperature range. The
frequency shift of the filter in the operating temperature range is included in the measurement 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.
