Characteristics
Remark:
The reference level for the relative attenuation arel of the TFS163A 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 reference 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 temperature coefficient of frequency Tc_f is valid both for the reference frequency fc and the
frequency response of the filter in the operating temperature range. The bandwidth shift of the filter in the operating temperature range is included in the
production tolerance scheme.

*) 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.
