Characteristics  
Remark:  
Reference level for the relative attenuation a of the TFS 1220B is the minimum of the pass band attenuation a  
. The minimum of the pass

rel  
band attenuation a  
is defined as the insertion loss a . The centre frequency f is the arithmetic mean value of the upper and lower frequencies  
min  
e c  
at the 3 dB filter attenuation level relative to the insertion loss a . The nominal frequency f is fixed at 1220,0 MHz without tolerance. The  
temperature coefficient of frequency Tcf is valid both for the frequency fc and the frequency response of the filter in the operating temperature  
rang.
