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.

You could check Agilent technical /application notes.
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
RF Circuit Fundamentals I and II: also by Les Besser.
have any PA matching and stability issues to clarify/discuss, I may
be able to help.

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

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

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
