Characteristics
Remark:
The reference level for the relative attenuation arel of the TFS 622A is the minimum attenuation in the pass band. The maximum attenuation in the pass
band is defined as the insertion loss ae. The nominal frequency fN is fixed at 622,08 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.
