2. Characteristics :
Remark: Reference level for the relative attenuation arel of the TFS 40 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 10 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.
