Providing Narrowband IoT Coverage With Low Earth Orbit SatellitesThis article describes the modeling of a SATCOM link, specifically the use case of using a satellite overlay to extend service continuity to IoT devices in a poorly covered rural area.
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.
