|| 0 pF || 0 pF
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 f c and the frequency response of the filter on the operating temperature range.
