This thesis investigates the design, analysis, and performance of BJT amplifiers in the 5-6 GHz range, a key spectrum for wireless communications, radar, and satellite systems. It covers fundamental amplifier principles, key metrics (efficiency, gain, bandwidth, noise figure, linearity), it compares BJTs and FETs for high-frequency applications. The BJT amplifier topology (common emitter) is analyzed for its suitability in the 5-6 GHz band.
The challenges include impedance matching, stability, thermal management, and noise reduction, while balancing trade-offs between gain, bandwidth, efficiency, and linearity.
The study highlights practical applications in wireless, radar, and satellite systems and discusses emerging trends in high-frequency amplifier design. It concludes with research contributions, limitations, and future directions for advancing 5-6 GHz amplifier technology.
