Characteristics
Remark:
Reference level for the relative attenuation
arel
of the
TFS 36B
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 reference frequence
fc
is the arithmetic mean value of the upper and lower frequencies at
the
40 dB
filter attenuation level relative to the insertion loss
ae.
The filter shall meet the specification at operating temperature.
