摘要

A wideband linearized amplifier includes first and second differential amplifier sections each including differentially connected first and second pairs of transistors and a linearizing element coupled between the emitters of first ones of the second pair of transistors of each of the first and second differential amplifier sections which cancels the non- linear effects of the base-emitter junctions of the transistors of the amplifier. The bases of the first pair of transistors of the first and second differential amplifier sections are respectively coupled to differential inputs of the amplifier while the bases of the second pair of transistors of the first and second differential amplifier sections are coupled to a reference potential. The collectors of the first pair of transistors and the first transistor of the second pair of transistors of the first differential amplifier section and the collector of the second one of the second pair of transistors of the second differential amplifier section are coupled to a first output of the amplifier while the collectors of the first pair of transistors and the first one of the second pair of transistors of the second differential amplifier section and the collector of the second one of the second pair of transistors of the first differential amplifier section are coupled to a second output of the amplifier.
