A good source for out of print technical books, and used current books,
is Powell's, http://www.powells.com.

which are the classics that the experienced members always
suggest


Microwave Transistor Amplifiers by Guillermo Gonzalez for small signal
design and Radio Frequency Transistors by Norm Dye and Helge Granberg for
power amplifier design. Don't know if the latter is still in print. Check
Opamp Technical Books at 1-800-468-4322.
