Modern SDRs evolve from configurable platforms into intelligent wideband sensing systems combining high dynamic range, ...

THE RADIO. It’s been around for more than 100 years. Pioneering work by Guglielmo Marconi and others in the1890s and 1900s resulted in practical wireless telegraphy devices that permitted ...

Characteristics of transceivers that combine analog, digital, and mixed-signal components, such as SDR, RFSoC/SoC, and DFE technologies. Basics of an SDR and RFSoC/SoC. The advantages/disadvantages of ...

Editor’s Note: This is a two-part series where DI authors Damian and Phoenix Bonicatto explore IQ signal representation and negative frequencies to ease the understanding and development of SDRs. Part ...

What is software defined radio (SDR) and how does it benefit modern communications and RF applications? RF/microwave PCB design for Radar and SDRs. Challenges of SDR PCB design and ways to overcome ...

Editor’s Note: This is the first article in a three-part series about software defined radios in GPS/GNSS simulators. Part 1: About GPS and various techniques that are used to advance signal ...

One of the best ways to learn about radios is to build your own, even in the age of cheap SDR dongles. [Aniss Oulhaci] demonstrates this with a simple HF SDR receiver built on a breadboard. An Arduino ...

Software Defined Radio (SDR) is the big thing these days, and why not? A single computer can get rid of a room full of boat anchors, and give you better signal discrimination than all but the best kit ...

The world around us hums with invisible signals, carrying everything from our favorite radio tunes to crucial communication data. At the heart of many of these wireless technologies lies the elegant ...

When testing devices that conform to multiple wireless standards, fast switching among waveforms is critical for keeping test times within reason. Keithley Instruments' Model 2910 400-MHz to 2.5-GHz ...
