Characteristics
Remark:
The reference level for the relative attenuation arel of the TFS 622C is the attenuation at nominal frequency. This value is defined as the insertion loss ae.
The nominal frequency fN is fixed at 622,08 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.
