1. 60 GHz Mixer and Multifunctional MMICs in GaAs pHEMT and mHEMT technologies
Sammanfattning : In recent years, the 60 GHz band has gained increased academic and commercial interest mainly due to the relative large amount of license free and little used frequency spectrum located in vicinity of 60 GHz. The exact locations of these free frequency bands varies locally but the 5962 GHz band overlap around the world and is therefore a true world wide license free band. LÄS MER
2. Mixers and Multifunctional MMICs for Millimeter-Wave Applications
Sammanfattning : This thesis treats the design and characterization of different mixer and multifunctional monolithic microwave integrated circuits (MMICs) in GaAs pHEMT and mHEMT technologies. The MMICs operate at the V (50 – 75 GHz) and G (140 – 220 GHz) bands and several of them demonstrate state-of-the-art performance, level of integration, novel topologies, and/or novel functionality.

3. Programmable and Tunable Circuits for Flexible RF Front Ends
Sammanfattning : Most of today’s microwave circuits are designed for specific function and specialneed. There is a growing trend to have flexible and reconfigurable circuits. Circuitsthat can be digitally programmed to achieve various functions based on specific needs. LÄS MER
4. Treatment with the monoclonal antibody rituximab in Multiple Sclerosis : a study based on an academic clinical trial
Sammanfattning : Background: Multiple sclerosis (MS) is a chronic, inflammatory disease, affecting the central nervous system. A growing number of disease modifying treatment alternatives entails a need for an individualised risk-benefit- convenience analysis in the counselling of patients and methods to monitor the treatment effect, including markers for subclinical inflammation.
