Remark:
The reference level for the relative attenuation a rel of the TFS 224A is the minimum of the pass band attenuation. This value is defined as the insertion
loss a e . The nominal frequency f N is fixed at 224,88 MHz without any tolerance. The values of relative attenuation a rel 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 parasites 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.
