There’s a problem with software defined radio. It’s not that everyone needs to re-learn what TEMPEST shielding is, and it’s not that Bluetooth is horribly broken. SDR’s biggest problem is one of ...

You’d be forgiven if you thought software defined radio (SDR) was a relatively recent discovery. After all, few outside of the hardcore amateur radio circles were even familiar with the concept until ...

After a prolonged and costly gestation, software-defined radio (SDR) technology is gaining ground. Airborne tactical networking radios, data links and relays based on SDR architectures are being ...

Software defined radio (SDR) has been one of your popular search topics this year on RF DesignLine. Recently I had the opportunity to hear from some people who are very active in this market: Frank ...

No doubt most tech and electronic enthusiasts have encountered buzz around SDR, software-defined radio, and asked themselves “what’s the sudden big deal,” if the technology existed for decades? The re ...

Chances are, you’ve actually used one without realizing it. I’m referring to a software-defined radio, and it is the design that most — if not all — modern radios, including automotive and home models ...

I want to get just a little technical this week and talk about how radios work. I’m going to avoid the detailed, low-level engineering stuff, apart from saying that designing radios is at least as ...

Software-defined radio (SDR) represents the future for some wireless technologies, but it's still a work in progress. Like any technology, it's followed an evolutionary path as components and ...
