2. Characteristics
Remark: Reference level for the relative attenuation
arel
of the
TFS 150N
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
. The temperature coefficient of frequency
Tc
f
is valid both for the
reference frequency
f c
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.
