Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 868H 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_N is fixed at 868,30 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_C 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_C

*) 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.
