Solid-State Power Amplifiers vs. Traveling Wave Tube Amplifiers

Viasat is leading a new wave of communications satellite innovation. This is a by-product of our belief that there is always a better way and not being satisfied with the “state-of-the-art” industry capabilities. It demands we think differently as we develop next generation technologies to enable satellite systems that are demonstratively better than have been offered in the past. Our unique industry position allows us to optimize the entire system, from the ground network to space payloads to user equipment. For high-throughput satellite payloads like ViaSat-1, ViaSat-2 and ViaSat-3, new technologies will need to be developed that get the industry beyond the status-quo and allow for orders of magnitude improvement in capacity and coverage area. We’ll discuss how new solid-state integrated circuit technologies are a tool that can be used to improve critical dimensions of performance for new satellite payloads.   (more)
