DAC38RF82: Power_level_below_500MHz

Anguraja Renganathan

Part Number: DAC38RF82

hi,

In datasheet, The output RF Power level graph is mentioned for above 500MHz output only.

Can please provide Output RF Power level Vs output Current and Output RF Power level vs SFDR details for DAC38RF82 below 500MHz?

thanks in advance

Hi Renga,

I have confirmed that we don't have much to offer from the datasheet below 500MHz and also production doesn't have anything to share either.

Can I ask what details, update rate, and other settings the customer would be interested in?

We can possibly run some power level and SFDR data in the lab for you once we understand the use case a bit better.

Regards,

Rob

Dear Rob,

Greetings, Can u run frequencies between 50MHZ to 500MHZ with interval of 10MHZ, Kindly provide SFDR and Power level along with those frequencies

thanks in advance

Anguraja,

At what DAC sample rate? Using the DAC PLL or an external clock? If using the DAC PLL, with what reference frequency? No NCO or interpolation, correct?

What LMFS setting?

I/Q data or real?

8-bit, 12-bit, or 16-bit mode?

Gain setting?

Regards,

Jim

Anguraja,

Here are some power numbers with the DAC sampling at 9GHz.
