Terminating impedances *:

Remark:

Reference level for the relative attenuation a rel of the TFS 70H25 is the insertion loss. The insertion loss a e is defined as the insertion loss at

the nominal frequency f n . The centre frequency f c is the arithmetic mean value of the upper and lower frequencies at the 3 dB filter attenuation

level relative to the insertion loss a e . The temperature coefficient of frequency Tc

response of the filter on the operating temperature.
