Abstract

A radio frequency (RF) transmitter architecture includes at least one digital signal processing module. The at least one digital signal processing module is configurable to operate in at least a first mode wherein the at least one digital signal processing module is arranged to receive a digital input signal, select, from a reduced set of digital power amplifier (DPA) control values, a plurality of DPA control values based at least partly on the received digital input signal, perform interpolation of the plurality of selected DPA control values to determine a DPA control value from a non-reduced set of DPA control values representative of the received digital input signal, and output to at least one DPA component the determined DPA control value representative of the received digital input signal.
