Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 780 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 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 fN is fixed at 780,0 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 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.
