Abstract
The invention concerns a circuit for multi-standard wireless RF transmission comprising: input circuitry (to) for generating a transmission signal (I(t), Q(t)) based on an input data signal (I, Q); a power amplifier () adapted to amplify said transmission signal to provide an output signal (S(t)) for transmission via at least one antenna; and feedback circuitry (to) comprising at least one variable low-pass filter () for generating a feedback signal (I, Q) based on said output signal, wherein said input circuitry further comprises pre-distortion circuitry () adapted to modify said input data signal (I, Q) based on said feedback signal.
