## Abstract This article presents a compact, high‐efficiency, spatially power‐combining system based on WR‐140 waveguide power dividers/combiners and microstrip probe transitions. Using four GaAs MMIC driver amplifiers and four MFET power amplifiers, the combining circuit produced up to 45‐W maximu
