1. 21. High frequency electronic packaging : SBU-materials, material characterization, simulation and processing

   Författare :Christian Johansson; Hjalmar Hesselbom; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dielectric loss; high frequency electrical characterization; microwave circuits; multilayer thin film technology; ORMOCER; permittivity; sequential build up; silicone elastomer;

   Sammanfattning : Electronic packaging continues to move towards improved performance and lower cost. Requirements of higher performance, reduced size, weight and cost of both High Density Interconnects (HDI) and high frequency (HF) devices has led to the search for new: materials, material combinations, methods, processes and production equipment.

The flakes are deposited from aqueous solutions and processed at low temperature. LÄS MER

5. 24. Silicon Carbide High Temperature Photodetectors and Image Sensor

   Författare :Shuoben Hou; Mikael Östling; Carl-Mikael Zetterling; Per-Erik Hellström; Anthony O'Neill; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon Carbide SiC ; high temperature; photodetector; photodiode; phototransistor; ultraviolet UV ; transistor-transistor logic TTL ; bipolar junction transistor BJT ; integrated circuit IC ; pixel sensor; image sensor; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : Silicon Carbide (SiC) has the advantages of ultraviolet (UV) sensing and high temperature characteristics because of its wide band gap. Both merits make SiC photodetectors very attractive in astronomy, oil drilling, combustion detection, biology and medical applications. LÄS MER

7. 25. Investigation of Sigma-Delta-over-Fiber for High-Capacity Wireless Communication Systems

   Författare :Husileng Bao; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; millimeter-wave; multipleinput- multiple-output; remote radio head; Radio-over-fiber; central unit;

   Sammanfattning : The advent of beyond-5G (B5G) and 6G technologies brings increases in wireless devices and their applications. Although massive multiple-input-multiple-output (MIMO) delivers high-capacity services using co-located MIMO (CMIMO) technology, distributed MIMO (D-MIMO) technology offers a more uniform user service.
