2. Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 52 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 fo is the arithmetic mean value of
the upper and lower frequencies at the 0,5 dB filter attenuation level relative to the insertion loss ae. The nominal frequency fN
is fixed on
52 MHz without tolerance or limit. The given values for the relative attenuation and for the phase linearity 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 of ± 10 kHz for the centre frequency fo . This frequency shift is
excluded both for the frequencies and limit lines given below.
