Abstract
Modern communication systems,while demanding high power efficiency, suffer from the inherent nonlinearty effects. Such a problem becomes more critical in LEO satellites, in which there are fundamental power limitations. Considering that the main source of nonlinear effects are power amplifiers, one of the most common methods to improve signal quality in a transmitter, meanwhile maintaining power efficiency, is to utilize linearization techniques for power amplifiers. This project consists of two parts. The first is to design and fabricate a power amplifier for the desired frequency (2.4 GHz) and power requirements (3 W). The other is design and fabrication of a linearizer and matching it to...
