12. Flexible Receivers in CMOS for Wireless Communication
Sammanfattning : Consumers are pushing for higher data rates to support more services that are introduced in mobile applications. As an example, a few years ago video-on-demand was only accessed through landlines, but today wireless devices are frequently used to stream video. LÄS MER
13. Development of SiC MESFET Based MMIC Technology
Sammanfattning : A SiC MESFET based MMIC process has been successfully developed. This technology has its main potential in high power microwave circuits. It will offer the benefits of the high integration seen in GaAs MMIC at the same time as it will offer the benefits of the high voltage operation seen in Si LDMOS and Si BJTs. LÄS MER
14. Wideband THz Mixers and Components for the Next Generation of Receivers for Radioastronomy
Sammanfattning : In recent decades, there has been a growing interest in THz research, leading to substantial improvements in technology and the emergence of new applications. In particular, the ever-evolving field of radio astronomy instrumentation has been pushing the limits of millimeter and sub-millimeter technology boundaries, redefining the state-of-the-art for wideband low-noise receivers.
