2. Heterostructure Barrier Varactors for High Efficiency Frequency Multipliers
Sammanfattning : This thesis describes the Heterostructure Barrier Varactor (HBV) and its application in frequency multipliers. Different HBV materials, fabrication processes, and device models are presented. The aim of this work is to improve the efficiency of HBV frequency multipliers. LÄS MER
3. Design, Fabrication and Analysis of InP-based Heterostructure Barrier Varactors
Sammanfattning : .... LÄS MER
4. 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
5. Fabrication of Integrated HBV Multipliers for THz Generation
Sammanfattning : The main objective of this licentiate thesis is to demonstrate silicon integrated HBV frequency multipliers for THz generation with RF performance comparable with InP technology. The choice of silicon is motivatedby better thermal and mechanical properties, cost and ease of integration compared to III-V semiconductor substrates. LÄS MER
