Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 868A1 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 f
is fixed at 868,92 MHz without tolerance. The given
values for the relative attenuation arel have to be reached at the frequencies given below even if the centre frequency f
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 f

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.
