HPM Broadband Tapered Transmitter Line Solid State Amplifier

Electronic Warfare (EW) is a critical component in conflicts around the globe. High Power Microwave applications need greater power and efficiency and wider bandwidth. Solid state technology is very capable and increased power by combining many devices improves overall performance. Diversified Technologies, Inc. (DTI) proposes to develop a wideband solid state power amplifier combining topology which has high efficiency and is compact. DTI will utilize an innovative general approach (wideband impedance transformation) with improved materials to combine the output power from a number of commercially available, low power transistors (hundreds of watts to a few kilowatts) into a single multi-kilowatt wideband output, with the technique applicable to a wide range of frequencies from L-band to X-band and beyond. In Phase I Base, DTI will design, fabricate full-scale hardware, and test the key components. The results will demonstrate the feasibility of the high power amplifier topology. In the Option, a brassboard device will be designed, fabricated, and tested with active RF transistors across several frequency bands. This will demonstrate feasibility of the wideband high power topology. Phase II will refine and improve the device performance and increase the frequency range at greater power. DTI already possesses the required administrative capabilities.
