Characteristics
Remark:
Reference level for the relative attenuation arel 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 469.99 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.
