Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 45 A is the minimum of the pass band attenuation amin. The minimum of the pass and
attenuation amin is defined as the insertion loss ae. The centre frequency fo is the arithmetic mean value of the upper and lower frequencies at the
3dB 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.
