Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 44N is the insertion loss. The insertion loss ae is defined as the insertion loss at the nominal
frequency fN . The centre frequency fc is the arithmetic mean value of the upper and lower frequencies at the 1 dB filter attenuation level relative to the
insertion loss ae. The temperature coefficient of frequency Tcf is valid for both the reference frequency fc and the frequency response of the filter in
operating temperature.
