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...

Moderator for the Circuits Forum - 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.

Greetings:

As you may have noticed, forum member IR has been a very active contributor to this Circuits forum. He brings more than six years of intense experience in the design of things like RF power amplifiers and transceivers.

IR has agreed to act as Moderator for the Circuits forum, which not only puts him in the limelight for fielding questions about circuit design/test issues, but also gives him the authority to edit message content. So, if you need a change made to your post, IR can do the job (and so can I).

This will be a good opportunity to make the Circuits forum a real learning experience for everyone since IR's enthusiam for circuit design extends beyond just the mentioned specialties, and includes filters, antennas, system analysis, oscillators, testing, and most other topics in the RF/microwave/analog realm.

Thanks to IR for taking on this role.

Greetings:

I apologize for the inconvenience of log in problems during the last week while moving the forum database. What should have been easy, was not. I believe all the issues have been resolved, but if you do experience a log in problem, please e-mail to me (kirtrfc@aol.com) and I will be happy to resolve it for you.

Thanks to IR for fielding the problems so far, but I want to relieve him from the burden and free up his time to field questions. Thanks again.

Greetings:

I forgot to mention that our excellent Circuits Forum moderator, IR, is on vacation through the end of the month. That is why his normal rapid response is not being seen this week. He has done a great job for us all while holding down a full-time engineering job during the day, so hopefully when he returns he'll be rested and ready to resume. Thanks for your patience.
