摘要： The present invention discloses a distributed power amplifier topology and device that efficiently and economically enhances the power output of an RF signal to be amplified. The power amplifier comprises a plurality of push-pull amplifiers interconnected in a novel circular geometry that preferably function as a first winding of an active transformer 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 that matches the geometry of 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 the RF, microwave, and millimeter-wave frequencies.

摘要： The invention is a radio transmitter that includes an antenna having at least one driven element and at least one reflector element. The driven element is electrically coupled to a radio carrier source. At least one of the driven elements or the at least one reflector element, includes at least one switch to modulate the radio carrier. Also, a secure communication system includes a radio transmitter configured to transmit a modulated signal within an information beam width. Also, a method for modulating a radio signal includes the steps of causing the transmitted carrier signal to be modulated by the modulation signal in response to switching the at least one reflector switch. Also, a method for selecting desirable antenna reflector switch combinations includes performing a mathematical simulation to determine whether the combination of reflector switch positions results in a modulated signal that can be demodulated within an information beam width.
