      M.Sc. Thesis: Active device modelling in microwave technologies Supervisor: Prof. Teresa M. Martín Guerrero My postgraduate Master Thesis research focused on the non-linear modelling process of a GaN 8x50 μm monolithic HEMT device. Practical issues on model selection and parameters extraction procedure were assessed. The model was validated both for small and large signal regime comparing measured and simulated results. Model efficiency was compared running an harmonic balance versus a time… Show more M.Sc. Thesis: Active device modelling in microwave technologies Supervisor: Prof. Teresa M.

      M.Sc. Thesis: The dual-fed metadistributed amplifier Supervisor: Prof. Carlos Camacho Peñalosa My Master Thesis evaluated the behaviour of the dual-fed distributed amplifier when the conventional artificial transmission lines are substituted by CRLH-TL (based on metamaterial concepts). The amplifier structure exhibit, under that condition, a band-pass behaviour that allows to extract maximum output power from the active devices for a given designable frequency.

      Ph.D. Thesis: The Power Recycling Distributed Amplifier Supervisors: Prof. Teresa M. Martín Guerrero and Prof. Carlos Camacho Peñalosa In my Ph.D. dissertation work a novel distributed amplifier structure based on a power recycling scheme was introduced. This new architecture allows the amplifier gain to be enhanced while providing optimum output power and a perfect input match within a moderate bandwidth. Conclusions derived from the theoretical analysis were validated through the design… Show more Ph.D. Thesis: The Power Recycling Distributed Amplifier Supervisors: Prof. Teresa M.

This new architecture allows the amplifier gain to be enhanced while providing optimum output power and a perfect input match within a moderate bandwidth. Conclusions derived from the theoretical analysis were validated through the design, manufacture and measure of a CRLH-TL-based prototype, which demonstrate the viability of the power recycling distributed amplifier as an optimum class-A active power combiner with enhanced gain and excellent input match.
