Patent ID: 7260418

Claim:
An N-element phased-array transmitter, each element of the phased-array further comprising: a pair of phase selectors each adapted to select one of an in-phase and a quadrature phase from a local oscillator signal and to supply the selected phases as output signals, wherein each phase of the local oscillator is selected from among M generated phases of the local oscillator; and a pair of RF mixers each associated with a different one of the pair of phase selectors and each adapted to receive the output signals supplied by its associated phase selectors and to generate a corresponding pair of RF signals using IF signals; a driver adapted to receive and process the generated RF signals supplied by the mixers; an amplifier adapted to amplify the RF signal processed by the driver; and a plurality of IF mixers adapted to receive in-phase and quadrature phase of a base band signal as well as divided-down phases of the local oscillator to generate the IF signals.
