Abstract
An RF transmitter comprises a digital-to-IF circuit block configured to receive a digital in-phase baseband signal and a digital quadrature baseband signal and to up-convert the digital in-phase and quadrature baseband signals to a digital in-phase IF signal and to a digital quadrature IF signal. The wireless RF transmitter further comprises an IF-to-RF circuit block configured to convert the digital in-phase and quadrature IF signals to analog signals and to up-convert the analog in-phase and quadrature IF signals to an RF output signal. The digital-to-IF circuit block comprises pre-compensation circuitry configured to reduce analog impairments associated with the IF-to-RF circuit block.
