    Abstract: PROBLEM TO BE SOLVED: To provide a distributed power amplifier topology and device, which efficiently and economically enhance the power output of an RF signal to be amplified.
    SOLUTION: The power amplifier includes a plurality of push-pull amplifiers mutually interconnected in a novel circular geometry, and preferably functions as a primary winding of an active element having signal inputs of adjacent amplification devices driven with an input signal of equal magnitude and opposite phase. The topology also discloses the use of a secondary winding 150 that matches the geometry of the primary winding and variations thereof that serve to efficiently combine the power of the individual power amplifiers. The novel architecture enables the design of low-cost, fully-integrated, high-power amplifiers in RF, microwave, and millimeter-wave frequencies.
