RF DAC for 6-12 GHz VCO control

Dear supporters,

 

I am interested in RF DAC for controlling 6-12 GHz VCO to generate frequencies sum of harmonics of 800 MHz and 6GHz (6.8GHz, 7.6 GHz...11.6 GHz) in LPLL with 800MHz reference for a sampling phase detector, and sweep the VCO in very narrow range close to sum of 800MHz Harmonics and 6GHz and stop sweeping when it is in the lock-in range(~12MHz), so that the pll can lock the frequency. Any recommendation for DAC selection would be appreciated.

 

Thank you.
