Abstract
An output stage () for a digital RF transmitter is provided. The output stage comprises: an input adapted to receive an input signal (RFin, b-b) to be transmitted; a plurality N of power amplification sections (S, S, S, S); and an output (A, B) providing an output voltage signal. Each of the N power amplification sections (S, S, S, S) is arranged to receive the input signal (RFin, b-b) and comprises a transformer (T, T, T, T) adapted to provide a respective output signal. Each transformer comprises a primary stage and a secondary stage; the secondary stages of the transformers (T, T, T, T) of the N power amplification sections (S, S, S, S) are combined such that a combined output voltage signal of the output stage is provided. The N power amplification sections (S, S, S, S) are adapted such that the input signal (RFin, b-b) is latched by clock signals (clock, clock, clock, clock) comprising different phases.
