Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 85 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 fo is the arithmetic mean value of the
upper and lower frequencies at the 3 dB filter attenuation level relative to the insertion loss ae. The nominal frequency fN is fixed
on 85,38 MHz without tolerance. The given values for the relative attenuation arel and for the group delay ripple have to be
reached at the frequencies given below also if the centre frequency fo 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 fo.
