Remark: The insertion loss a is defined as the insertion loss at the nominal frequency fN . Reference level for the relative attenuation a  
of the

TFH 70D is the insertion loss. The reference frequency f is the arithmetic mean value of the upper and lower frequencies at the 3 dB filter  
c
attenuation level relative to the insertion loss a . The temperature coefficient of frequency Tcf is valid both for the centre frequency f and the  
e

frequency response of the filter in the operating temperature range. The frequency shift of the filter in the operating temperature range is included in  
the production tolerance scheme.
