1. Modelling and design of high-power HBV multipliers
Sammanfattning : This thesis deals with symmetric varactor frequency multipliers for millimetre and sub-millimetre wave applications. Much of the material presented is general and applicable to any type of (symmetric) varactor, but the focus is on the heterostructure barrier varactor (HBV). The basic function and principles of HBVs are explained. LÄS MER
2. HBV frequency multiplier 2D arrays and application
Sammanfattning : The utilisation of the THz spectrum ( 0.3-3 THz ) is hampered by technological difficulties to generate power at these frequencies. LÄS MER
3. Modelling of Terahertz Planar Schottky Diodes
Sammanfattning : This thesis deals with the modelling of THz planar Schottky diodes, focusing on analyses of the geometry- dependent parasitics and the diode chip thermal management. Moving towards higher operating frequencies, the electromagnetic couplings pose significant limitations on the diode performance. LÄS MER
4. Silicon Integrated HBV Frequency Multipliers for THz Applications
Sammanfattning : This thesis deals with integrated varactor diode circuits for terahertz (THz) applications. In particular hybrid, monolithic microwave integrated circuits (MMICs), and heterogeneous integration are explored for frequency multiplier applications. LÄS MER
5. 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
