2. Characteristics
Remark:
Reference level for the relative attenuation arel of the
TFD 70 Q
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
20 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.
