Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS82B 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 nominal frequency is fixed on 82 MHz. The
centre frequency f0 is the arithmetic mean value of the upper and lower frequencies at the 3 dB filter attenuation level relative
to the insertion loss ae.
