Title: Traveling wave power combining apparatus

Abstract: A solid state power combining apparatus for use in a microwave transmission system. The apparatus includes a distributed amplifier having an input transmission line, an output transmission line, and a plurality of amplifiers connected between the input and output transmission lines at quarter wavelength intervals. The phase relationship between the traveling waves placed on the output transmission line from the amplifiers is such that the waves placed on the output transmission line by the amplifiers in the direction toward an output terminal add and the waves placed on the output transmission line by adjacent amplifiers in the direction away from the output terminal cancel each other. Also, a solid state power combining apparatus wherein a plurality of oscillators are connected between input and output transmission lines at quarter wavelength intervals. A phase relationship similar to that of the distributed amplifier apparatus is provided when the oscillators are injection locked in response to an input signal.
