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...

Matching for PAs - 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.

Can someone tell me the best online tutorial for impedance matching of PAs. If you find there is someother means to get educated about matching and stability analysis of PAs, that would be great.

Hi :

You could check Agilent technical /application notes.
And may I suggest that you find RF textbooks. Most of RF textbooks should be able to help you...

Here are some recommendations :

1. Microwave Transistor Amplifiers, by Guillermo Gonzales
2. RF Circuit Fundamentals I and II: also by Les Besser.

If you have any PA matching and stability issues to clarify/discuss, I may be able to help.

hi jean...what do u think abt 'Microwave and RF Power Amplifier Design' book? have u ever used it or do u know if it's a good one to have or nothing beats Microwave Transistor Amplifiers?? Thanks

Hi there..

In my opinion, it depends on what issues do you need to emphasize more.
If for general knowledge on stability and matching networks, I believe most of RF textbooks will provide good information on this issue.

I think, this RF Cafe provides good information on this issue as well.

And I found lectures of 'RF and Microwave Power Amplifier Design' By Andrei Grebennikov, M/A-COM Eurotec.

which I believe gives you some information on your interest issues, as it covers stability, gain (Lecture 3) and impedance matching (Lecture 2), that are important issues on PA Design fundamentals.

I'm not sure whether you are looking for general knowledge or something more advanced?

If you have some issues to discuss, I might be able to help.

jean...the book i mentioned is by Andrei Grebennikov of M/A-COM, Ireland. the thing is that i'm starting research in PA IC design and although i've lots of academic background in analog/RF design and RFIC design i particularly don't have much knowledge of hardcore PA design. Stability, gain, matching network....i've very sound foundation there but more important issue relating to PA design, especially IC design is what i'm really looking for and i though 'RF and Microwave PA design' might be a good book to use as a guide and reference. thanks
