Remark:  
Reference level for the relative attenuation a of the TFS 120A is the insertion loss. The insertion loss a is defined as the insertion loss at the nominal  
rel  
e
frequency f . The centre frequency f is the arithmetic mean value of the upper and lower frequencies at the 3 dB filter attenuation level relative to the  
N
C
insertion loss a . The temperature coefficient of frequency Tcf is valid for both the reference frequency f and the frequency response of the filter on the

operating temperature.
