Hello,

Can anyone please help me to clear my doubt?

I want the quadrature DDS with atleast 250 MHz of bandwidth. Out of all the quadrature DDS available AD9854 is the only with max 120 MHz bandwidth. Can anyone recommend me the chirp generation of 250MHz bandwidth?

or if i use AD9854 for IQ signal at baseband and increase the bandwidth by PLL is it possible? I want IQ signal at X band with 250 MHz bandwidth.

I m just a beginner , can someone please help me urgently?

THANKS in advance.
