What is the residual phase noise of mixers LTC5510 and LTC5549 (LTC5549 with enabled LO frequency doubler)?
We don't have any data for this for our RF mixers, and no way to measure it at this time.

Thank you for your reply, Weston Sapia!
Please share if you ever measure it.
A couple more questions:
What technology is used to fabricate built-in amplifier (as well as doubler) in these mixers - SiGe, GaAs ...?
For LTC5549 - what insertion loss expected at RF frequency 15 GHz and LO frequency 12 GHz (doubler enabled)?
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.
Thank you very much, Weston Sapia!
I also found an article in which there is a paragraph about technology LTC5549 (SiGe BiCMOS). It should have a relatively low additional phase noise.

What about LTC5510, It is also SiGe?
The LTC5510 is also done in SiGe.
