  • Multi-standard wireless transmitter
    Patent number: 9178538
    Abstract: The invention concerns a circuit for multi-standard wireless RF transmission comprising: input circuitry (302 to 314) for generating a transmission signal (IT(t), QT(t)) based on an input data signal (I, Q); a power amplifier (316) adapted to amplify said transmission signal to provide an output signal (S(t)) for transmission via at least one antenna; and feedback circuitry (320 to 340) comprising at least one variable low-pass filter (334, 336) for generating a feedback signal (IFB, QFB) based on said output signal, wherein said input circuitry further comprises pre-distortion circuitry (302) adapted to modify said input data signal (I, Q) based on said feedback signal.
