Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 533 is the attenuation at 533 MHz. The nominal frequency fN is fixed at 533 MHz
without tolerance. The centre frequency fc is the arithmetic mean value of the upper and lower frequencies at the 30 dB filter attenuation level
relative to the insertion loss ae. 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.
