Rf power amplifier design thesis

The classes are based on the proportion of each input cycle conduction angle during which an amplifying device passes current. The angle of flow is closely related to the amplifier power efficiency. In the illustrations below, a bipolar junction transistor is shown as the amplifying device.

The main objective of any power amplifier research is to increase the efficiency while maintaining linearity and broadening the frequency of operation.

The main motivation for the renewed interest in PA technology comes from the technical challenges and the economics of modern digital communication systems. Modern communications require high linear power amplifiers and in order to reduce the complete system cost, it is necessary to have a single broadband power amplifier, which can amplify multiple carriers.

Rf power amplifier design thesis

The improvement in the efficiency of the power amplifier increases the battery life and also reduces the cooling requirements for the same output power. In this thesis, I aim to design and build a wideband class J power amplifier suitable for modern communications.

For wideband operation of the GaN technology PA, a bandwidth extension design method is studied and implemented.
