DAC38RF83: Using 2nd Nyquist

Izik

Part Number: DAC38RF83

Hello

I would like to use the DAC38RF83 with sampling clock = 7.8GSPS, and output CW using SPI at the second Nyquist, range 5100-6000MHz.

Do you have any information regarding the performance under these or similar conditions?

Especially would like to know:

Ouput power

SFDR

Additive Phase noise

Thanks

Hi Izik,

Output power will be less than -10dBm mostly due to power loss to sinx/x rolloff
The phase noise is also expected to degrade by an additional -10.5dB at 6GHz from the plot in datasheet at 1.8GHz.

Thanks,
Eben.
