Abstract:
1. A mixed-signal RF power amplification system comprising: an RF signal source receiving baseband digital data, the RF signal source comprising an in-band digital predistortion circuit and a digital-to-RF modulator to modulate the baseband digital data onto a carrier signal to provide a modulated RF signal; an RF power amplifier module to amplify the modulated RF signal, the RF power amplifier module comprising an RF power amplifier and an RF power amplifier linearizer with an RF predistortion circuit; a signal path to transmit the modulated RF signal from the RF signal source to the RF power amplifier module; and a data path providing an interface to exchange control data between the RF signal source and the RF power amplifier module to allow joint adaptation of the RF signal source and the RF power amplifier module.
