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 Tc
f
is valid for both the reference frequency fc and the frequency
response of the filter on the operating temperature range
.
