Abstract
An HBT amplifier with a "post-distortion"-type linearizer utilizing a base-collector junction diode shows more than 8dB improvement of adjacent channel power ratio, and the collector linearizer comprising a reverse biased basecollector junction diode requires no additional dc power consumption and has no deterioration of RF performance. The linearization technique of post-distortion compensates the nonlinearity of HBTs, which arises from the C bc variation due to a large-signal swing.
