Characteristics
Remark:
The reference level for the relative attenuation arel of the TFS 552A is the minimum of the pass band attenuation. This value is defined as the insertion loss
ae. The nominal frequency fN is fixed at 552 MHz without any tolerance. 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.

only. Should there be additional questions do not hesitate to ask for an application note or contact our design team.
