2. Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 135C is the insertion loss. 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 3 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.
