Characteristics
Remark:
Reference level for the relative attenuation are_l of the TFS 326A 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 f_c 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 f_N is fixed on 326,4 MHz without tolerance.
