What do you get when you combine a direct digital synthesis (DDS) chip, a power detector, and an Arduino? [Brett Killion] did make that combination and wound up with a practical network analyzer. T… ...

Makers, hobbyists and developers looking for a low powered Arduino compatible development board with built-in RF capable of running AVR projects ...

“We’re trying to create an Arduino for the RF sector; a board that’s low cost, powerful, exceptionally flexible and easy to use. And, most importantly, we’re trying to let the community determine what ...

We peeked at the schematic and the shield is more for letting the Arduino control the radio by changing the oscillator frequency rather than performing the SDR functions.
