A transmission circuit includes a shift circuit, a second shift circuit, and a modulation circuit. The shift circuit is configured to select a shift amount according to shift parameters and to introduce the shift amount in a first direction into in phase and quadrature phase baseband signals. The second circuit is configured to selectively introduce the shift amount in a second direction into local oscillator signals. The modulation circuit is configured to modulate the shifted baseband signals onto the shifted local oscillator signals to generate a composite modulated output signal. Unwanted components of the output signal are shifted away from original or specified limits. Wanted components of the output signal are unshifted.

Systems and methods to frequency shift unwanted signal components

A signal processing circuit for providing a modulated analog transmit signal on the basis of a digital transmit data signal is disclosed. The signal processing circuit includes one or more digital circuit components and one or more analog circuit components, and is configured to vary a bias voltage or a supply voltage of at least one of the one or more digital circuit components or at least one of the one or more analog circuit components in dependence on a detected or predefined parameter when providing the modulated analog transmit signal. The detected or predefined parameter includes a parametric or environmental condition associated with the signal processing circuit.
