Characteristics
Remark:
The reference level for the relative attenuation arel of the TFS125T is the minimum of the pass band attenuation. This value is defined
as the insertion loss ae. The nominal frequency fN is fixed at 125 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.
