This specification consists of four sheets
Measurement condition
Ambient temperature:
23 °C
Input power level:
-10 dBm
Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 110 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.
