1. A method for amplifying diversity transmit signals, comprising:

  • receiving a transmit signal at a vector modulator, the vector modulator operable to process the transmit signal to yield a plurality of diversity transmit signals by;

    splitting the transmit signal to yield at least two transmit signals;

    adjusting a phase of at least one of the at least two transmit signals;

    adjusting the amplitude of at least one of the at least two transmit signals; and

    generating the plurality of diversity transmit signals according to the adjusted transmit signals;

    amplifying each of the plurality of diversity transmit signals according to a gain using at least one power amplifier; and

    transmitting the plurality of amplified diversity transmit signals at a plurality of antennas.
