2. Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 36B 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 frequence fc is the arithmetic mean value of the upper and lower frequencies at
the 40 dB filter attenuation level relative to the insertion loss ae. The filter shall meet the specification at operating temperature.
