Hi FJ and welcome to the forums.

You might get a better response if you post this in a different forum than Introductions.

Hi freakyjason85. Welcome to the forum.

When i read rf amp, i read "radio frequency" amp. If that is true, i don't think there's a lot of reading here.
But.... There's a lot of capable persons i'm sure 🙂

Good luck and best regards
Ebbe

To me your question sounds like, "How to swim?" It's a complex question.

Anyway, if what you mean with "RF Amp" is something like 2.4Ghz amplifier, or 1.5Ghz GPS LNA. You should check Avago. They made easy to use MMIC. No discrete transistor.

All you need is to know is:
1. How to do impendance matching or microstrip basic.
2. Proper biasing of MMIC
3. And the hardest part, the antenna.
