Abstract :
Recent work in active quasi-optical coupled arrays have shown this technology to be a feasible and promising method for achieving efficient and high-power solid state power combining. Quasi-optical techniques should find greatest use at millimeter-wave frequencies where waveguide circuits are lossy and difficult to build. In this paper, we examine some of the advantages of this technology and review the recent developments in active grid arrays. Because of their versatility, special emphasis is given to transistor grids and their use as oscillators and amplifiers
