Thank you very much for your enthusiastic reply. But Hittite HMC220MS8
is not satietied with our design. Because we convert RF 5.8GHz to IF
3.5GHz. So LO frequency shall be 2.3GHz. But Hittite HMC220MS8 LO&RF
are 5GHz above. Hope you can help we to find other mixer IC or advise.
Thank you very much again! Top yendori Post subject:

I were you, which I am, I would make a simple single ended mixer. Just
create the bandpass filters and diplexers and tht's it. You will
be completly satietied. Unless size and performance is an issue.
Keep in mind you can apply the LO to the IF port for most double
balanced mixers. In fact, you can interchange any port as long it's
within the specified frequency response. There will also be trade-offs
in performance...loss, isolation, linearity etc. If you'd
like I can design a mixer for you. I'm quite the mixer guy, I even have
a few mixer patents. the women are very impressed.
