The following is excerpted from Chapter 18: Software Defined Radio from the Book, RF & Wireless Technologies by Bruce Fette. If you order a copy of this book before December 31, 2007 you can receive ...

If you haven’t heard about Software-Defined Radio (SDR) by now, you certainly will soon enough. The idea behind SDR has been around for over 30 years, but it’s only recently that it has started to ...

Making a software defined radio (SDR) receiver is a relatively straightforward process, given the right radio front end electronics and analogue-to-digital converters. Two separate data streams are ...

Nextbigfuture was able to ask Rob Hoyt of Tethers Unlimited how he will be able to use 27 large high low-earth orbit satellites to provide high-speed internet directly to smartphones. The GlobalFi ...

Software defined radio or SDR is the most exciting frontier in the field of radio, transferring as it does all signal functions from the analogue to the digital domain. Radios using SDR techniques can ...

Fig 1. A conventional legacy radio receiver (a) uses the standard analog superheterodyne architecture with analog circuitry performing all functions. A more advanced superheterodyne receiver (b) uses ...

CML Micro, a leading developer of mixed-signal, RF, and microwave semiconductors for global communications markets, is pleased to announce the launch of the CMX918, an advanced, ultra-low-power, multi ...

There is a new breed of RF receivers known as software-defined radios, and they are revolutionizing the way in which people listen to shortwave (SW) radio, or indeed any form of radio broadcast. SDRs ...

The creation of true software-defined-radio (SDR) systems has been made possible by the digitization of traditionally analog RF hardware. SDRs have been under development for many years. Now, they are ...

CML Micro has launched the CMX918, an advanced, ultra-low-power, multi-mode Software-Defined Radio (SDR) tuner designed to significantly extend battery life in portable, embedded, and always-on radio ...

Convergence also creates problems. Radio frequencies and handset features are increasing as convergence to the multifunction device continues. Each time something is added, the handset needs more ...

CML Micro has launched the CMX918, an ultra‑low‑power, multi‑mode Software‑Defined Radio (SDR) tuner designed to extend battery life in portable, embedded and always‑on radio applications.
