High-frequency, high-power transistor linear power amplifier design.

Abstract

This thesis discusses in detail the physical and electrical characteristics of high-frequency, high-power transistors, and why class B amplifiers are necessary for linear power amplification of signals containing more than one frequency. Linear power amplifier design is contingent upon having a suitable design technique. "Suitable" often means being able to determine parameter values called for by that technique. Conjugate impedance matching is a suitable technique and three of the four parameter values can be accurately determined. In some cases manufacturers provide data for this technique, titled "Large-signal-parameters".
