Input power level:
Terminating impedances in fc:
2. Characteristics
Remark:
Reference level for the relative attenuation
arel
of the
TFS 140 D
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 frequency
fc
is the arithmetic mean value of the upper and lower
frequencies at the
3 dB
filter attenuation level relative to the insertion loss
ae
.
