2. Characteristics
Remark: Reference level for the relative attenuation arel of the TFS 140A 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 20 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. The frequency shift of the filter in the operating
temperature range is not included in the production tolerance scheme.
