Remark:
Reference level for the relative attenuation arel of the TFS 86 C is the minimum of the pass band attenuation amin. The minimum of the pass
band attenuation amin is defined as the insertion loss ae. The centre frequency fc is the arithmetic mean value of the upper and lower frequencies
at the 3dB filter attenuation level relative to the insertion loss ae. The nominal frequency fN is fixed at 86,46 MHz without any tolerance. The given
values for the relative attenuation arel and for the group delay ripple have to be reached at the frequencies given below even if the centre
frequency fc is shifted due to the temperature coefficient of frequency TCf in the operating temperature range and due to a production tolerance
for the centre frequency fc.
