Summary: | 碩士 === 國立交通大學 === 電信工程研究所 === 104 === This thesis consists of two parts, including power amplifiers with Parallel, Series, Parallel-Series power combining transformers and a 5-GHz GaN low noise amplifier.
In the first part, fully-Integrated high linearity power amplifiers implemented with TSMC 0.18-m SiGe BiCMOS technology are presented. The improvement of output power and linearity is achieved using parallel, series, parallel-series power combining transformers to combine the power of multiple power cells. Furthermore, a 5-GHz high/low mode power amplifier with parallel power combining transformer not only improves output power and linearity but also enhances efficiency.
The second part introduces GaN technology and a 5-GHz GaN low noise amplifier with GaN technology is demonstrated with low noise figure.
