  5. 3. Design and Fabrication of Silicon Carbide RF MOSFET for L- and S-band applications

    Author : Gudjon Gudjonsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Metal-Oxide-Semiconductor Field-Effect-Transistor MOSFET ; 4H-SiC; Silicon Carbide SiC ;

    Abstract : This thesis describes realisation of 4H-SiC radio-frequency metal-oxide-semiconductor field effect transistors (RF MOSFETs). Such transistors are in principle very attractive devices for high power and high frequency electronics. They are intended as a direct replacement for their silicon counterparts, offering higher power. READ MORE
