1. Mixers and Multifunctional MMICs for Millimeter-Wave Applications
Abstract : 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.

2. 60 GHz Mixer and Multifunctional MMICs in GaAs pHEMT and mHEMT technologies
Abstract : 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. READ MORE
