Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 190 D is the insertion loss. The insertion loss ae is defined as the minimum of
attenuation in pass band. 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 nominal frequency f
N
is fixed on 190,000 MHz without tolerance. The given values for the relative
attenuation arel and for the group delay ripple have to be reached at the frequencies given below also 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.
