Remark:

Reference level for the relative attenuation a

of the TFS 246 M is the minimum of the pass band attenuation a

. The minimum of the pass band

rel

attenuation a

min

is defined as the insertion loss a . The centre frequency f is the arithmetic mean value of the upper and lower frequencies at the 3 dB

e c

filter attenuation level relative to the insertion loss a . The nominal frequency f is fixed on 246 MHz without tolerance. The given values for the relative

attenuation a and for the group delay have to be reached at the frequencies given below even if the centre frequency f is shifted due to the temperature

rel

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