Abstract
The application of the passivity theory to the radio-frequency (RF) power-amplifier (PA) linearization problem leads to a new structure that is capable to being built completely with analog circuitry. In this paper, the basis of the passivity (or hyperstability) theory are revised and applied to the linearization of an RF power amplifier, proposing the resulting linearizer structure and experimenting with it from simulations based on the RF PA experimentally validated by Saleh and from a real model of a Class A PA operating at 28 GHz.
