UWB LNA THESIS

Advanced design techniques, for example electromagnetic simulations of the entire layout of the LNA module were utilized. Finally, UWB bias networks implemented with different microstrip elements were studied. Experimental results confirm the simulation results based on the LNA design with distributed matching networks. Using one antenna for each sub-band and an LNA designed for maximum-flat power gain provides equal performance within the entire frequency band. However, if a wideband operation is required, the issue must be solved with other techniques. The nonidealities of the broadband matching networks implemented with microstrips are analyzed and their effects on the LNA performances are presented. Klas Eriksson ; [] Keywords:

Low-Noise Amplifier Design for Ultra-Wideband Systems

Lnq, if a wideband operation is required, the issue must be solved with other techniques. Advanced design techniques, for example electromagnetic simulations of the entire layout of the LNA module were utilized. As a first step the design methodology focuses on noise figure optimization and continues with the optimization of the power gain.

The simulated LNA using microstrip matching networks achieved a noise figure smaller than 2.
