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

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

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

Hello songbo,

Here is an example for an IC mixer from Hittite Microwave:

Hittite Microwave has more examples of Mixers, take a look at their website: www.hittite.com

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.
