Hello Bob,
I would like to know which ADI products or platforms are suitable for which application. Is SDR limited to Military usage or it can be used in automotive or Consumer devices too.
RE: ADI Products Suitable for Software Defined Radio? by ADIApproved:
Hi,
Software Defined radio (SDR) is where some of all of the signal chain is in software; the technique can be used in military, automotive, or consumer, though there are dedicated chipsets for consumer AM-FM radios and some other applications. SDR comes into its own economically when the application is multimode and a single software-based modulator/demodulator is more economical than dedicated hardware demodulators. Arguably almost any part we make can be used at RF, IF, or baseband or in supporting circuitry like the power supply so there really aren't SDR-specific parts and yes ADI makes LOTS of parts for SDR. For instance, some SDRs used by such public safety personnel as firefighters use accelerometers to detect lack of motion to send out an alert that the user may be hurt or trapped.
I created a set of wideband and narrowband SDR signal chains for our military web site that can equally be used for a variety of communications applications, whether they be consumer, automotive, or military. It really depends on the application and desired price/performance ratio.
The complete set of signal chains can be found on this page:

The narrowband IF-sampling receiver using the AD9864 is a good starting point for communications receivers; if you were to build a modern version of, say, the Zenith Transoceanic Shortwave Receiver (a 1950s-vintage multiband radio) I'd start there. If you wanted to design a high performance car radio I'd start with the same signal chain. Many RF instruments use a similar signal chain.

Bob
