Characteristics

Remark:

Reference level for the relative attenuation arel of the TFS 86 A1 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 3

dB filter attenuation level relative to the insertion loss ae. The nominal frequency fN is fixed on 86,85 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 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.
