Characteristics
Remark:
The reference level for the relative attenuation arel of TFS 70L9 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.
