  2. 1. Microwave power device characterization

    Author : Kristoffer Andersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; statistical estimation; self-heating; Silicon Carbide; Gallium Nitride; mixer; thermal resistance; wide bandgap; microwave; error-correction; small-signalmodel;

    Abstract : The first part of the thesis covers work done on device characterizationmethods. A statistical method for estimating small-signal model parametersin FET-models was proposed. A maximum likelihood estimator wasderived and the new method was compared to a standard direct extractiontechnique. READ MORE

  4. 2. Integrated Antennas : Monolithic and Hybrid Approaches

    Author : Erik Öjefors; Anders Rydberg; Sayan Mukherjee; Duixian Liu; Uppsala universitet; []
    Keywords : Electronics; antenna travelling wave arrays; antenna phased arrays; phase shifters; micromachining; silicon; monolithic microwave integrated circuits; dipole antennas; loop antennas; slot antennas; Elektronik;

    Abstract : This thesis considers integration of antennas and active electronics manufactured on the same substrate. The main topic is on-chip antennas for commercial silicon processes, but hybrid integration using printed circuit board technology is also addressed. READ MORE

  6. 4. Tuneable Recursive Active Monolithic Microwave Integrated Circuit Filters

    Author : Robert Malmqvist; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In this thesis tuneable recursive active monolithic microwave integrated circuit (MMIC) filters are studied theoretically and experimentally. A possible future application for such filters is, for example, the microwave receivers of adaptive radar antennas. READ MORE

  7. 5. Applications of monolithic fiber interferometers and actively controlled fibers

    Author : Patrik Rugeland; Fredrik Laurell; Walter Margulis; Miguel Andrés; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fiber; fiber Bragg grating; micro-structured fiber; add drop multiplexer; fiber interferometer; microwave photonics; temperature sensor;

    Abstract : The objective of this thesis was to develop applications of monolithic fiber devices and actively controlled fibers. A special twin-core fiber known as a ‘Gemini’ fiber was used to construct equal arm-length fiber interferometers, impervious to temperature and mechanical perturbations. READ MORE
