Remark:
Reference level for the relative attenuation a rel of the TFS 225 A is the minimum of the pass band attenuation a min . The minimum of the pass
band attenuation a min is defined as the insertion loss a e . The centre frequency f c is the arithmetic mean value of the upper and lower frequencies at
the 3 dB filter attenuation level relative to the insertion loss a e . The given values 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 .
