2. Characteristics
Remark:
Reference level for the relative attenuation a rel of the TFS 120A is the insertion loss. The insertion loss ae 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 d B filter attenuation level relative to the insertion loss a e. 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 .
