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 typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

System design software - 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. 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.

Can anyone recommed a good (and inexpensive) program for doing RF system design work? I looked at an eval version of SysCalc, but it looks a little pricey for what you get. Anything else out there? Anyone have a used copy of SysCalc to sell for a couple hundred bucks?

Dear troy,

Have you tried the RFcafe-Calculator-Workbook?

If you need free system simulators you can try QUCs. You can also use appcad. Thanks.

Best Regards,

You would be amazed what you can do with Excel and VBA :-)

except for complex math (a+jb)*(x+jy)

For serious work with field calculations you need Mathcad or Fortran
