Characteristics

Remark:

Reference level for the relative attenuation a rel of the TFS 208C is the maximum of the pass band attenuation a max . The maximum of the pass

band attenuation a max is defined as the insertion loss a e . The centre frequence f c is the arithmetic mean value of the upper and lower frequencies

at the 1 dB filter attenuation level relative to the insertion loss a e . The nominal frequency

for the relative attenuation a rel and for the group delay ripple have to be reached at the frequencies given below also if the centre frequency f c is

shifted due to the temperature coefficient of frequency TC f in the operating temperature range and due to a production tolerance for the centre

frequency f c .
