RF transistor amplifier design, any suitable literature?

Yansi:
Hello!

Let's say I have a bunch of these nice RF transistors: 2SC5773 Datasheet
and I want to build an RF amplifier for a say 145MHz band. I have only basic understanding of a LF common emitter amplifier, including some basic models and in/out impedance calculation. However these basics do not apply at RF frequencies well and also I need a 50ohm matching for the in- and output of the amplifier.

What steps do I need to design such transistor amplifier matched both sides to 50ohms, at such (or any other) frequency?
Can you please recommend any suitable literature or appnotes, related to this topic, how is this done?

Thank you for help or any recommendations.

"Radio frequency transistors" by Dye and Granburg is a good one for this sort of thing.

Of course, some works on RF circuit design in general do also hold information pertaining to this area.

Some app notes:

"S-Parameter Techniques for Faster, More Accurate Network Design":
http://www.hparchive.com/Application_Notes/HP-AN-95-1.pdf

"S-parameter design":
http://www.sss-mag.com/pdf/AN154.pdf

You'll notice from the Renesas data sheet that this transistor has an S21 of more than 25dB at 145MHz.  So all you have to do is bias it and you will have a ton of gain in a 50 ohm system.

You'll also notice that the above app notes don't even tell you how to bias it.  They assume you can figure that out.  Your biggest problem with biasing will be keeping it from oscillating.

A book I had long ago and probably long out of print.  Not sure I would really recommend it:
"Design of Amplifiers and Oscillators by the S-parameter Method" by Vendelin:
