Characteristics
Remark:
Reference level for the relative attenuation arel of the TFH 44C 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 3 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 on the operating temperature.
