DDS Success

We redesigned the DDS (Direct Digital Synthesizer) for prototype II because it wasn’t meeting design goals for phase noise after being up-converted to our 740MHz LO.

LO = (Fout-IF)*2

Noise present in the LO appears in the final output and limits the amount of amplification available. This is why many HTs and other integrated radio products cannot be attached to power amps and stay legally in the channel.

The new design is working now and tests show adequate margin to take this design to production. This is a significant milestone behind us and puts us one large step forward to production.
