Realization of ultrawideband linear microwave low noise amplifier

During the last decade, stimulated by unprecedented growth in the wireless communication application, outstanding progress has been made in the development of low-cost solutions for front-end RF and microwave systems. This growing demand has further forced microwave amplifiers to widen their bandwidth. Widening bandwidth has become a pressing issue for microwave circuit designers. Today, broadband and ultra-wideband amplifiers are one of most researched topics of microwave engineering.In this study, I aimed to design an ultra-wideband low noise amplifier utilizing in-hand technology. I had to take in to consideration to what I could reach, and that, inevitably, had a huge impact on my design and realization process. In the paper I firstly focused on theoretical background of microwave amplifier design. Then, I had demonstrated that PSO can be successfully employed for a design of matching circuit for ultra-wideband applications. In this work I had extensively utilized PSO code developed by Asst. Prof. Dr. Salih DEMİREL and Prof. Dr. Filiz GÜNEŞ.
