Defined Radio (SDR) has taken the communications world by storm in the last decade. SDR attempts to
minimize the amount of fixed, non-reconfigurable content in a radio and to maximize the amount of
reconfigurable content. At first, doing so meant using digital signal processing (DSP) technology to
handle the detection, demodulation, and processing of RF signals, but still relying on fixed front end
circuits and antennas for initial reception. Now, as integrated circuit (IC) technology gets ever faster
and more sophisticated, at sub-microwave frequencies the incoming signals are being sampled and
downconverted without the need for mixers, local oscillators, filter banks, and associated circuitry.
Even fixed antennas are sometimes being replaced with electronically steered phased arrays - in some
cases integrated right onto the IC.
Cognitive radio exploits the capability provided by SDR to
add an intelligent, adaptive nature to operations. It is capable of learning how to most effectively use
its features and reconfiguring modes of operation to be the most effective and efficient. These are
exciting times in the radio realm.
It is difficult to find vendors who make devices specifically marketed as SDR components, but most of the
top name and even a lot of specialty companies are slowly listing SDR and cognitive radio as potential
applications for their products.

Product distributors and sales representatives are not listed (they have their own page). This helps guarantee that each
listing offers a unique product or service. NOTICE: I am no longer adding hyperlinks. Your best bet is to use a search
