Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 433 E is the maximum of the pass band 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 3 dB filter attenuation level relative to the insertion loss ae. The nominal frequency fN is fixed on 433,92 MHz without
tolerance. The given values for the relative attenuation 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.
