| Summary: | Thesis (MTech(Electrical Engineering))--Cape Peninsula University of Technology, 2006. === Electronic communication systems have become an integral part of our everyday lives. RF
(Radio Frequency) power amplifiers form part of the fundamental building blocks of an
electronic communication system. RF power amplifiers can also be one of the major causes
of distortion in an electronic communication system.
This thesis describes the linearity requirement for a RF power amplifier that is used in a
transmitter section of an electronic communication system. Furthermore, five different
linearisation techniques are presented and their characteristics compared. Since a power
amplifier employing the Feedforward linearisation technique was designed, built and tested,
this thesis focuses on the Feedforward technique.
The design methods for the various Feedforward components are presented. The measured
parameters of the Feedforward linearised amplifier are compared with the measured parameters
of a non-linearised amplifier.
