Characteristics
Remark:
The reference level for the relative attenuation arel of the TFS 170N is the attenuation at nominal frequency f_N. The maximum attenuation in the pass band
is defined as the insertion loss ae. The nominal frequency f_N is fixed at 170,6 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.
