Abstract
The present invention describes a phased array transmitter and a method for beamforming. The phased array transmitter comprises a plurality of transmitting branches configured for up-converting an IF signal to an RF signal with a desired RF phase shift. Each transmitting branch is configured for phase shifting the IF signal with a first phase shift and the LO signal with a second phase shift such that the combined first and second phase shift is the desired RF phase shift of the transmitting branch.
