Abstract

See full text

A linearized amplifier comprising a RF input for receiving a modulated signal and a RF output for supplying a linearly amplified modulated signal. The RF input is connected to a first junction. The linearized amplifier further comprises a linearizer having an input connected to the first junction and a output connected to a second junction. The first junction defines a first path connected to the second junction through the linearizer for linearizing the modulated signal at a first defined range of power and a second path connected to the second junction bypassing the linearizer at a second defined range of power. The linearized amplifier further comprises a amplifier having a input connected to the second junction and a output connected to the RF output for supplying the linearly amplified modulated signal.
