Patent ID: 7349679

Claim:
A power amplifier to provide a high power output signal comprising: a plurality of voltage controlled oscillators, each voltage controlled oscillator includes a plurality of input control signal terminals to communicate received phase synchronizing control signals from an adjacent voltage control oscillators of the plurality of voltage control oscillators and a plurality output control signal terminals to communicate transmitted phase control signals to said adjacent voltage control oscillators and a first output signal terminal to transmit a first output signal such that said received phase synchronizing control signals adjusts a phase synchronizing for said first output signal with all of the plurality of said voltage controlled oscillators; a plurality of first buffer circuits, each first buffer circuit is comprised of an input terminal and an output terminal, said input terminal receiving the first output signal from one voltage controlled oscillator, said buffer circuit amplifying and conditioning said first output signal from one voltage controlled oscillator and transmitting said amplified and conditioned first output signal from said output terminal; and a signal combining circuit in communication with the buffer circuit receives the amplified and conditioned first output signals, combines said amplified and conditioned first signals to generate said high power output signal.
