Abstract
A radio frequency (RF) power amplifier circuit with a diode linearizer circuit. The power amplifier circuit has an input and an output, as well as a power amplifier transistor with a first terminal connected to the input, a second terminal connected to the output, and a third terminal. The linearizer circuit is connected to the third terminal and to ground, and has a non-linear current-voltage curve as well as a non-linear capacitance. The linearizer circuit reduces inter-modulation products in a current through the power amplifier transistor from the second terminal to the third terminal that corresponds to an input signal applied to the input.
