1. MMIC FET frequency doublers and FMCW radar transceivers
Sammanfattning : .... LÄS MER
2. Microwave FET Modeling and Applications
Sammanfattning : This thesis deals with three distinct topics within the areas of modeling, analysis and circuit design with microwave field effect transistors (FETs). First, the extraction of FET small-signal model parameters is addressed. LÄS MER
3. Millimetre wave waveguide enclosed grid frequency multipliers and imaging
Sammanfattning : The utilisation of the THz spectrum ( 0.3-10 THz ) is hampered by fundamental difficulties in generating power at these frequencies. LÄS MER
4. Millimeter and Sub-Millimeter Wave Integrated Active Frequency Down-Converters
Sammanfattning : In recent years, the increasing amount of data transmission, the need for automotiveradars, and standoff imaging for security applications are the main factors that accelerateresearch in the millimeter and sub-millimeter wave frequency ranges. The semiconductorindustries have continuously developed their processes, which have opened upopportunities for manufacturing monolithically integrated circuits up to a few hundredGHz, based on transistor technologies.
