2. Characteristics
Remark:
Reference level for the relative attenuation
arel
of the
TFS 140C
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
3 dB
filter attenuation level relative to the insertion loss
ae.
The temperature coefficient of frequency
Tc
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.
