Characteristics
Remark:
Reference level for the relative attenuation a
of the TFS82B is the minimum of the pass band attenuation a . The
min
rel
is defined as the insertion loss a . The nominal frequency is fixed on 82 MHz. The
minimum of the pass band attenuation a
min
e
centre frequency f is the arithmetic mean value of the upper and lower frequencies at the 3 dB filter attenuation level relative
0
to the insertion loss a .
