ACCURACY OF NOISE
FIGURE MEASUREMENT
SYSTEMS (

Abstract: This paper describes methods of evaluating the
accuracy of noise figure measurement systems for the microwave
frequency range. It also discusses a transistor noise figure
test, and SSB and DSB testing. Included are actual plots of
data taken from typical test systems. In addition, comments
are presented for use of programmable impedance equipment
which permits generation of noise figure circles for amplifier
design work.
