Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 341 B is the minimum of the pass band attenuation amin. The minimum of the pass band
attenuation amin is defined as the insertion loss ae. The centre frequency fo is the arithmetic mean value of the upper and lower frequencies at the
2 dB filter attenuation level relative to the insertion loss ae. The given values for the relative attenuation arel and for the group delay ripple have to
be reached at the frequencies given below also if the centre frequency fo is shifted due to the temperature coefficient of frequency TCf in the
operating temperature range and due to a production tolerance for the centre frequency fo.
