Armoring Satellites To Survive And Operate Through Attacks
Satellites do a lot of things — they help people navigate from one place to another, they deliver television programming, they search for new stars and exo-planets and they enable the U.S. nuclear deterrence strategy. But until recently, one thing they haven’t done — or needed to do — is defend themselves.

Automotive Radio Frequencies Poster
Mobile communications, Wi-Fi, V2X, C-V2X, navigation, radar, broadcast and EV charging are just some of the applications occupying automotive radio frequencies. Being able to manage coexistence and interference of various radio frequencies has become a major challenge for research, development, and testing. Download this poster to get an overview of the radio frequency bands and regulations in today's and tomorrow's cars.
The Doherty Amplifier is used in an increasing number of radio transmitter applications to improve energy efficiency. There are numerous ways to build the Doherty PA. This article begins with an overview of linearization and efficiency enhancement in Doherty amplifiers, highlights the associated challenges, and covers some of the numerous solutions for design.
Filters are a staple of RF designers everywhere, and especially in applications where the integrity of the signal cannot be compromised. When you’re only concerned about a single frequency, it’s relatively easy to add in a fixed-tuned filter. However, it becomes slightly more difficult when you need to cover multiple frequencies and can’t just utilize a roofing filter. To avoid having to use a bunch of individual filters, basically creating a complex switched filter bank module, a tunable filter may be the solution.
The Wi-Fi Alliance has introduced the newest generation of Wi-Fi technology — Wi-Fi 6. This application note discusses Wi-Fi 6, how it will reduce power consumption, and how antennas and antenna systems must perform to function successfully in a Wi-Fi 6 world.
Qorvo discusses the design layouts for a 3GHz, 25 Gbps DOCSIS with 1.8 GHz ESD as a steppingstone. Considerations on power consumption, coexistence with FDX, spectrum plans and interference from MoCA, LTE and Wi-Fi are discussed.
