Remark:
Reference level for the relative attenuation
arel
of the
TFS 454
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
o
is the arithmetic mean value of the upper and lower frequencies at the
3dB
filter attenuation level relative to the insertion loss
ae
. The nominal frequency
fN
is fixed at
454,00 MHz
without tolerance. The given values for the relative
attenuation
arel
and for the group delay ripple have to be reached at the frequencies given below even if the centre frequency
fc
is shifted due to the
temperature coefficient of frequency
TCf
in the operating temperature range and due to a production tolerance for the centre frequency
