KX3 IQ ADC and IQ DAC specification?

[Elecraft mailing list]

I am trying to determine the IQ ADC and IQ DAC specification in the KX3.    I'm interested in
determinng how many bits and the speed...Bit resolution and samples per second?  

Thanks
 

John, W1QS

Judging by the anti-aliasing filters, I would guess maybe 48k samples per second, 24 bits per sample. Could be higher at 96k which could reduce noise slightly via decimation, but that would probably consume extra power and not be worth it. But does it really matter? That is all internal to the radio, and is not exposed on any of the external interfaces.

Hello John!

The components used are shown in the KX3 schematics available on the
Elecraft website.  You can get whatever specifications your are
interested in about those components from the manufacturer's data
sheets.  The sampling rate currently being used, subject (but unlikely)
to change is 48 kHz.
