1. 1. Microwave Power Devices and Amplifiers for Radars and Communication Systems

   Författare :Sher Azam; Qamar ul Wahab; Erik Janzén; Georg Boeck; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Semiconductor physics; Halvledarfysik;

   Sammanfattning : SiC MESFETs and GaN HEMTs posses an enormous potential in power amplifiers at microwave frequencies due to their wide bandgap features of high electric field strength, high electron saturation velocity and high operating temperature. The high power density combined with the comparably high impedance attainable by these devices also offers new possibilities for wideband power microwave systems. LÄS MER
