2. Characteristics
Remark:
Reference level for the relative attenuation
arel
of the
TFS 100
A 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
33 dB
filter attenuation level relative to the insertion loss
ae.
The temperature coefficient of frequency
Tc
f
is valid both for
the reference frequency
fc
and the frequency response of the filter in the operating temperature range. The frequency shift of the filter in the
operating temperature range is not included in the production tolerance scheme.
