Characteristics
Remark:
The reference level for the relative attenuation arel of the TFS150T 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 fc and the
frequency response of the filter in the operating temperature range. The bandwidth shift of the filter in the operating temperature range is included in the
production tolerance scheme.
