Remark:
Reference level for the relative attenuation a rel of the TFS 235A is the insertion loss. The insertion loss a e is defined as the minimum of
attenuation in pass band. 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 nominal frequency f
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 .
