Preliminary specification
TFS 140 A - 1/2
1. Measurement condition
Ambient temperature T
A
:
Input power level:
Terminating impedances in fc:
2. Characteristics
Remark:
Reference level for the relative attenuation arel of the
TFS 140 A
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 frequence 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.
