Abstract
A spatial power divider/combiner that comprises: a housing containing a first channel forming three sides of a rectangular input waveguide and a second channel forming three sides of a rectangular output waveguide; a board coupled to the housing, wherein the underside of the board forms the fourth side of the input and output waveguides; a series of slots etched on the underside of the board located in the input waveguide to divide an input signal; a series of slots etched on the underside of the board located in the output waveguide to recombine the divided signal; and a series of microstrip lines printed on the top side of the board to couple the input waveguide and the output waveguide. Additionally, the divider/combiner can comprise a series of active devices, such as MMIC power amplifier, to provide a spatial power amplifier.
