Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 111 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 30 dB filter attenuation level relative to the insertion loss ae. The temperature coefficient of frequency Tcf is valid both for the reference
frequency fc and the frequency response of the filter in the operating temperature range.
