Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 211 A 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 reference frequency fc is the arithmetic mean value of the upper and lower frequencies at
the 3 dB filter attenuation level relative to the insertion loss ae. The peak to peak pass band ripple is the maximum attenuation level difference
between adjacent local minima and local maxima of the pass band. This ripple is only measured if more than one local maxima or minima exist. The
values below are guaranteed in the whole operating temperature range.
