LTC5510 and LTC5549 residual phase noise

Hi,

What is the residual phase noise of mixers LTC5510 and LTC5549 (LTC5549 with enabled LO frequency doubler)?

Parents
  • The entire mixer is done in SiGe.

    The LTC5549 is not recommended for use above 14GHz on the RF port. I would suggest that you take a look at the LTC5553, which is a higher frequency version of the LTC5549. Unfortunately, this part does not have the LO doubler on chip, however.

    Thanks,
