Characteristics
Remark:
Reference level for the relative attenuation a of the TFS 471 is the maximum of the pass band attenuation a
. The maximum of the attenuation
max
rel
within the usable signal bandwidth is defined as the insertion loss a . The centre frequency f is the arithmetic mean value of the upper and lower
frequencies at the 3dB filter attenuation level relative to the insertion loss a . The nominal frequency f is fixed on 471,55 MHz without tolerance.
The given values for the relative attenuation a and for the group delay ripple have to be reached at the frequencies given below also if the centre
frequency f is shifted due to the temperature coefficient of frequency TC in the operating temperature range and due to a production tolerance for
