- Recent LANL activities in millimeter wave structures focus on 94 and 300 GHz structures. They aim at power generation from low power (100-2000W) with a round electron beam (120kV, 0.1-1.0 A) to high power (2-100 kW) with a sheet-beam structure (120 kV, 20 A). Applications cover basic research, radar and secure communications and remote sensing of biological and chemical agents. While for round beams rf-structure and powercoupler design are fairly straightforward, for the sheet-beam structure (aspect ratio ≈ 12), especially the power coupler design is more challenging. In this paper the design of a complex, non-linear converter/combiner power-coupler and its match to the rf-structure will be presented.
