Characteristics
Remark:
The reference level for the relative attenuation arel of the TFS155A is the maximum attenuation in the pass band. The maximum attenuation in the pass
band is defined as the insertion loss ae. The nominal frequency fN is fixed at 155,52 MHz MHz without any tolerance or limit. The values of relative
attenuation arel are guaranteed for the whole operating temperature range. The frequency 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.
