    Författare :Ahmed Adel Hassona; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; interconnects; THz; taper; waveguide transition; MMIC; InP; WR-6.5.; slot antenna; CMOS; eWLB; LTSA; finline; millimeter-wave; SiC; D-band; GaAs;

    Sammanfattning : Fueled by the increasing demand for higher data rates, millimeter-wave (mmW) systems emerged as a candidate that can provide multi-gigabit per second (Gb/s) transmission. This demand is mainly driven by modern communication systems and several other wireless and sensing applications such as production quality inspection and imaging systems. LÄS MER

  5. 4. Microwave power device characterization

    Författare :Kristoffer Andersson; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
