regulators and clocks - nice work. sounds like a recipe for success .
sounds like all bases are covered.
,... Yes, US is finally catching up to the rest of the world (but STILL
perhaps 10uW ?!) The rest of the world is at 0.5uW or less for two way
radio.....

Oops. I haven't memorized that uV to dBm table yet.
Regarding the frequency control and regulators, we have the DAC/ADC
clocks and frequency synthesizers all running off of one oscillator.
The computer is on a separate module that we don't make. Each of
digital power and analog power are set up as two stages with a
wide-voltage-range regulator making 5V and then that feeds multiple
3.3 regulators. VCOs have their own regulators separate from the rest
of analog. We do not use the IF oscillator in the CMX991 because it
has parasitics at audio. There are separate digital and analog ground
planes and a single-point ground at the antenna connector.
Thanks
Bruce
