Abstract

A transmitter circuit has a signal input for receiving an analog input signal and a local oscillator (LO) input for receiving an LO signal. A mixer circuit has a first input, a second input, and an output. The second input of the mixer circuit is connected to a signal input of the transmitter circuit. A PA circuit has an input connected to the output of the mixer circuit, and an output. A control circuit generates a phase-control signal and a gain-control signal in response to an envelope of the analog input signal. A phase-control circuit generates a phase-adjusted LO signal in response to the LO signal and the phase-control signal and supplies the phase-adjusted LO signal to the first input of the mixer circuit. A gain-control circuit controls a gain of the transmitter circuit in response to the gain-control signal.
