Characteristics
Remark:
The reference level for the relative attenuation arel of the TFS156D is the minimum attenuation in the pass band. The minimum attenuation in the pass band
is defined as the insertion loss ae. The nominal frequency fN is fixed at 156.25 MHz without any tolerance or limit. 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.
