    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...

800Mhz - 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.

Hi all,

I am a beginner in RF. I need to build a 880MHz upconverter - downconverter pair. I have serached and found MMIC on mixer and a suggested PCB is given in the datasheet. Is it easy to make it or I should buy a module instead of component. Please give me your advice.

Hittie has many mixers that cost ~$1.00. They also offer evaluation boards, which they will either give or sell to you. The evaluation boards have the connectors, DC pins and are ready to use. Modules typically are much more expensive.

Thanks for your advice. Because this project is funded by university. Money is not a big problem. I need to build FM system for testing. Any expert can guide me how to find the sources?

Because you are from a university, Hittite may give you the samples boards for free. I would check out their website, and then contact their sales department. Their support is excellent, unlike other companies, they will actually speak with you and truly try and solve your problems.
