Sammanfattning : This thesis describes heterostructure barrier varactor (HBV) frequency multipliers for millimetre and sub-millimetre wave applications.The basic principles of HBVs are explained. Starting from basic varactor theory, an equivalent circuit model for HBVs is presented. LÄS MER
Sammanfattning : This thesis deals with fabrication, characterisation and modelling of the Heterostructure Barrier Varactor (HBV) diode and its use in frequency multiplier circuits. Different aspects of material structures and frequency multipliers are described. LÄS MER
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
Sammanfattning : The utilisation of the THz spectrum ( 0.3-3 THz ) is hampered by technological difficulties to generate power at these frequencies. LÄS MER
Sammanfattning : The utilisation of the THz spectrum ( 0.3-10 THz ) is hampered by fundamental difficulties in generating power at these frequencies. LÄS MER
