The article says: "The Pizzicato digital radio transmitter consists of an integrated circuit outputting a single stream of bits, and an antenna ".
That doesn't sound like 'Purely from Microprocessor Tech' to me. It sounds like a strap-on peripheral chip, which is not at all 'Purely microprocessor.'
Most of the people commenting on this story have no clue about signal processing or radios. It is quite possible to feed a "stream of bits" to an analog filter and create a clean analog signal. This is effectively what 1-bit delta-sigma data converters do, and it is close to what Class-D audio amplifiers do. The trick is indeed doing this with wide bandwidth signals and sufficient oversampling to have good signal quality. To get wide bandwidth at 5GHz, they probably are running the sampling rate in the GH
What you say is plenty familiar to some of us, but RTFA and you'll see that it gives no technical clue as to what their innovative contribution is. It just sounds like it was written to attract uninformed investors.
Well, they'd better have something to show... From the release: "Cambridge Consultants is demonstrating Pizzicato at Mobile World Congress in Barcelona, March 2-5, stand 7B21 in Hall 7."

No actual info in article, just hype and buzzwords.

You mean like IoT? I cringe when I see that lol.
