21. Microwave and Millimeter-Wave Monolithic Integrated Circuits in CMOS and GaAs-mHEMT Technologies
Sammanfattning : The objective of this work has been to design and characterize microwave and millimeter-wave components and circuits within a 90 nm Si-CMOS process and a 100 nm GaAs-mHEMT process. The work is divided in two parts depending on the technology. LÄS MER
22. Flip-Chip Interconnect for Millimeter-Wave Packaging Applications
Sammanfattning : In recent years, with the demands for wireless communication systems increas rapidly, the operating frequency for the portable wireless is moving toward millimeter-waves. Millimeter-wave wireless communication systems require not only suitable functional IC components but also competent package with low cost and good interconnect performance. LÄS MER
23. GaN HEMT Based Highly Integrated Active Antenna Element for Millimeter-Wave Array Transmitters
Sammanfattning : .... LÄS MER
24. Location-aided Beam Alignment and Handover in Millimeter-wave Networks
Sammanfattning : Ever-increasing data rate demands in mobile networks and the spectrum scarcity at the microwave bands have resulted in the exploration of millimeter-wave (mmWave) frequencies for the next generation of wireless networks. While mmWave frequencies offer large bandwidth, communication at these frequencies is not straightforward due to the challenging propagation characteristics. LÄS MER
25. 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
