Characteristics
Remark:
The reference level for the relative attenuation arel of the TFS155B is the minimum of the pass band attenuation. This value is defined as the insertion loss
ae. The nominal frequency fN is fixed at 155,52 MHz without any tolerance. The values of relative attenuation arel are guaranteed over the whole operating
temperature range. The frequency shift of the filter within 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.
