Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 228 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 fc is the arithmetic mean value of the upper and lower frequencies at the
1 dB filter attenuation level relative to the insertion loss ae. The given values for the relative attenuation arel and for the group delay ripple have to
be
reached
at
the
frequencies
given
below
also
if
the
centre
frequency
f
C
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 fc.
