Characteristics
Remark:
The reference level for the relative attenuation arel of the TFS 140AS 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 20 dB
filter attenuation level relative to the insertion loss ae. The nominal frequency fN is fixed at 140,0 MHz without any tolerance. The shift of the filter band
width in the operating temperature range (OTR) 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.
