Abstract :
A novel method employing a current source load lineariser is introduced to enhance the nonlinear performance of an HBT low-noise amplifier. This load compensates for the nonlinear behaviour of the amplifying transistor; obtaining a highly linear amplifier, achieving an IIP3 close to 20 dB and showing an independent test tone spacing behaviour.
