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...

Surface Mount Isolator? - 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.

I am looking for a chip Isolator. 10 dB isolation at 900 MHz would be nice with less than 1 dB insertion loss. I want the smallest package possible. Anyone know of any suitable parts?

Hello RF Head,

I found some Isolators in M/A-COM website.

Here is an example:

http://www.macom.com/DataSheets/FR32%20 ... ASHEET.pdf

The selection guide of MA/COM can be found here:

http://www.macom.com/psc/jsp/ListParts. ... lators.txt

Amother great source for components search is
''RF Cafe Parts List'', it will be very useful for your search.

Here is the Isolatorsand Circulators page from there:

https://www.rfcafe.com/vendors/component ... lators.htm

Hope this helps.
