Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 471 C is the maximum of the attenuation amax. The maximum of the attenuation within
the usable signal bandwidth is defined as the insertion loss ae. The centre frequency fo 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 on 471,55 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
