1. Device Technology Based on High Temperature Superconductors and Microwave Breakdown in Gases
Sammanfattning : This thesis deals with two separate fields of microwave technology. The first section treats microwave characterization and applications of high temperature superconducting (HTS) thin films, while the second section treats microwave breakdown in transmit-receive (TR) switches and in air. Within the first section, four main topics are adressed. LÄS MER
2. Wide Bandgap MMIC Technology
Sammanfattning : Wide bandgap technology for microwave electronics has been an intense area of research during the last decade. With reas of application ranging from base station amplifiers to radar transceivers, this technology has the resources to be the basis for the next generation of high power microwave electronics.

3. Integrated millimeter Wave CMOS Power Amplifiers for 5G Systems
Sammanfattning : The anticipated continuation of the last three decades of growth of global demand for high-speed high-coverage mobile data, calls for massive investments in cellular infrastructure, for the ongoing roll out of the fifth generation of mobile systems, but also later for the sixth generation. A key enabler, for the high-speed part, is for the cellular system to move up in frequency and support communication at millimeter-wave (mmW) frequencies (24 – 70 GHz), where available wideband spectrum exist.
