    Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Please help me to find my need mixer IC type - RF Cafe Forums

RF Cafe Forums closed its virtual doors in 2012 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2010, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. If the folks at phpBB would release a version with integrated sign-in from the major social media platforms, I would resurrect the RF Cafe Forums, but until then it is probably not worth the effort. Regardless, there are still lots of great posts in the archive that ware worth looking at.

Below are the old forum threads, including responses to the original posts.

Hittite Microwave has more examples of Mixers, take a look at their website:

Good Luck!

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!

If 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.
