Characteristics
Remark:
The reference level for the relative attenuation arel of TFS117 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 3 dB filter attenuation level
relative to the insertion loss ae. The given values for the relative attenuation arel and the group delay ripple have to be reached at the frequencies
given below, even if the centre frequency fc is shifted due to the temperature coefficient of frequency TCf in the operating temperature range and
due to a production tolerance for the centre frequency fc.

*) 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.
