1. A method for generating an ultra wideband signal that has a phase shift at every cycle, the method comprising:
- generating a first tone that has a frequency one half of a desired frequency of the ultra wideband signal, wherein the ultra wideband signal is a sine wave that inverts phase every cycle;
generating a second tone that has a frequency three halves of the desired frequency;
amplifying the first and second tones independently to generate an amplified first tone and an amplified second tone; and
combining the first and second amplified tones to form the ultra wideband signal.

Abstract
A method and system to create an ultra wideband (UWB) signal are disclosed. The UWB signal comprises a carrier frequency with each cycle reversing in phase. The UWB signal is generated from a limited number of high power narrow band amplifiers. Each amplifier'"'"'s output signal is combined to produce the desired UWB signal. The combination may occur in a combiner network or in free space.
