TFS 70H38 1/5
Remark:
Reference level for the relative attenuation arel of the TFS 70H38 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 range.
