Abstract
A quasi-optical power combining array provides broadband, well heat sinked performance by means of coupling an array of parallel slotline transition modules between a input waveguide and an output waveguide. Each slotline transition module is comprised of a heat sinked ceramic substrate upon which a pair of tapered slot transitions is defined, each of which lead to a quasi-optical element such as an amplifier, which in turn is coupled to a corresponding pair of tapered slot transitions leading to the output waveguide. Each slotline module is symmetrically formed to maximize input and output tuning and selectively balanced operation.
