Characteristics
Remark:
The reference level for the relative attenuation arel of the TFS 182 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 fc is the arithmetic mean value of the upper and lower frequencies at the 20 dB
filter attenuation level relative to the insertion loss ae. The frequency shift of the filter in the operating temperature range is not included in the production
tolerance scheme.
