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...

PCB layout and design tutorials - 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,

I've been trying to find material on PCB design and fabrication online but without any luck. Any help would be appreciated.

Thanx again...

Hi,
For PCB layout software and fabrication, try:

www.pcb123.com
www.free-pcb-software.com
www.expresspcb.com

I hope this is what you want - if not, could you be more specific?

Thanks, and
Good Luck!

Hi,

I need to construct a PCB power amplifier (designed to handle PEP of 300W) for a coupling unit topology, which in turn is to be used for Powerline Communication Networks. There are PCB milling machines in my department.

I would like to get some tips on implementing this high power PCB design (this is my first time), any precautions to be observed and useful material online or in the form of books.

Thanx again.. You have been really helpful..

EE major.

Hello EE_Major,

The best advice I can give you would be to go to Freescale website and find out an example for an Evaluation Board (EVB) for an RF Power Transistor :!:

The data sheet of the device usually contains the Bill of Materials of the EVB including components values and also the PCB layout of the board and the substrate it is made of. In many cases, the substrate being used is ROGERS 4003/4350 but there are sometimes exceptions.

You can find a lot of useful information in their website.

Good luck, should you need more information please let me know. :)
