1. Dynamic response reconstruction using passive components
Sammanfattning : In many testing applications within the field of structural dynamics, such as noise and vibration harshness, rattle and squeak, or durability testing in the automotive and truck industries, large hydraulic or electromagnetic actuators are used to excite the tested structure. Such actuators are mounted in the laboratory in a fixed configuration referred to here as a test rig. LÄS MER
2. Passive microwave components for Silicon MMICs : design, modeling and measurements
Sammanfattning : .... LÄS MER
3. Intermodulation Distortion in Active and Passive Components
Sammanfattning : Wireless communication is growing rapidly, and the demand for higher data rate, low latency, and availability leads to a more complex infrastructure with new challenges. Multiple communication systems have to co-exist in a densely populated frequency-spectrum, where higher power levels and more sensitive receivers are required. LÄS MER
4. Towards Ultimate Performance of THz Heterodyne Receivers: SIS Frequency Multiplier and Wideband Passive Components
Sammanfattning : This thesis focuses on the development of advanced components for the future wideband side band separating and / or multipixel receivers for radio-astronomy with ultimate sensitivity.In this thesis, a novel frequency multiplier based on distributed superconducting tunnel (SIS) junctions has been demonstrated for the first time, taking advantage of the extreme inherent nonlinearity of such device.

5. Integrated Lumped Element and Ferroelectrically Tunable Microwave Components
Sammanfattning : This thesis treats the development of passive circuits for increased integrationlevel in microwave front-ends. The subject is approached from twodifferent directions. On the one hand, emerging materials for microwaveintegrated circuits are studied. On the other hand, novel circuit topologiesare synthesized. LÄS MER
