2. Characteristics :
Remark: Reference level for the relative attenuation arel of the TFS 70H16 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.
