First Fully Digital Radio Transmitter Built Purely From Microprocessor Tech

Posted by samzenpus on from the new-way-to-listen dept.

Zothecula writes For the first time in history, a prototype radio has been created that is claimed to be completely digital, generating high-frequency radio waves purely through the use of integrated circuits and a set of patented algorithms without using conventional analog radio circuits in any way whatsoever. This breakthrough technology promises to vastly improve the wireless communications capabilities of everything from 5G mobile technology to the multitude devices aimed at supporting the Internet of Things (IoT).

  1. The trick is a clean signal with no harmonics by Anonymous Coward · · Score: 2, Interesting

    No problem generating RF with digital circuits; it has been done for decades. The trick is to generate clean frequencies with no significant harmonic content and no spurs. Now perhaps the cicuits used in this article are digital and analog on one silicon substrate. Certainly a DAC can be made using a semiconductor resistor network fabbed on the same substrate as the digital electronics. And capacitors and inductors can be fabbed on a silicon substrate. I would like to see the details of what they are actually doing. "Pure digital" sounds like a phony to me.

    I could build a "Fully Digital Radio Transmitter" in a few minutes using a Crystal and a CMOS gate.
