Shi, K. (author)With the rapid growth of wireless communication systems, there is more and more demand for radio frequency power amplifiers (RFPAs) in base stations to be power-efficient so as to reduce the cooling and electrical power cost. Besides the efficient requirement, wide-band working frequency and compact PCB size are also attractive for cutting more...master thesis 2010

Zhang, R. (author)This research work aims to gain understanding of the power amplifier (PA) operating as a linear PA under low power drive conditions and as a switch-mode PA in high power drive conditions both with the same Class-E load. Two approaches were taken here. Firstly, an analytical approach was developed to investigate the switching operation of...master thesis 2010

Kearey, R.F. (author)This thesis describes the design, simulation and implementation of a supply modulator to be used in a VHF power amplifier on the Delfi-n3Xt nano-satellite. First, a set of specifications is defined that describe the required functionality. These are derived from earlier work on related systems and confirmed through discussions within the project...master thesis 2010
