Remark:
Reference level for the relative attenuation a rel of the TFS 211 A is the minimum of the pass band attenuation a min . The minimum of the pass band
attenuation a min is defined as the insertion loss a e . The reference frequency f c is the arithmetic mean value of the upper and lower frequencies at
the 3 dB filter attenuation level relative to the insertion loss a e . 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.
