Characteristics
Remark:
The reference level for the relative attenuation arel of the TFS 940C is the maximum attenuation in the pass band. The maximum attenuation in the pass
band is defined as the insertion loss ae. The nominal frequency f_N is fixed at 940 MHz without any tolerance or limit. 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.
