I need to generate a sinusoidal signal sweep...
The ideal band from 300KHz to 20GHz - smooth & clean, low-power for a medical application.
The compromise band is 500MHz to 20GHz.
I think a step resolution of 25KHz would work..
Between the ADI and HMC pll/vco/dividers, and DSS options
I could use some direction in the RF design space.
Power is paramount (portable device).
Simplicity. Contiguous/unswitched op preferred.
