11. Millimeter-wave Transceiver ICs for Ultrahigh Data Rate Communications Using Advanced III-V and Silicon Technologies
Sammanfattning : Today’s main driving parameter for radio transceiver research is the ability to provide high capacity while maintaining low cost, small form factor, and low power consumption. Direct conversion architectures (due to the feasibility of monolithic integration) at millimeter-wave (due to wideband availability) have attracted large interest in recent years because of their potential to meet these demands.

12. InP HEMT Technology and Applications
Sammanfattning : Indium phosphide high electron mobility transistors (InGaAs/InAlAs/InP HEMTs) exhibit the highest cut-off frequencies and the lowest microwave noise figures of all transistor technologies. Both InP HEMT technology and associated circuit demonstrators are therefore interesting to explore further. LÄS MER
13. Ultra-Low Noise InP HEMTs for Cryogenic Amplification
Sammanfattning : InGaAs/InAlAs/InP High Electron Mobility Transistors (InP HEMTs), are today the best devices to design cryogenic low noise amplifiers. However, reported progress in reducing the noise has been slow in the last decade. LÄS MER
14. RF and Noise Optimization of Pseudomorphic inP HEMT Technology
Sammanfattning : The InGaAs-InAlAs-InP high electron mobility transistor (InP HEMT) is the electronic device utilized for the highest frequency and/or the lowest noise applications known to date for analog transistor-based circuits. Hence it is of both scientific and technological interest to explore the InP HEMT for even further improvement in device performance. LÄS MER
15. Broadband Wireless OFDM Systems
Sammanfattning : While the readiness of the telecommunication market and the users' need for broadband mobile data are not currently noticeable, a set of presented megatrends and scenarios suggest that broadband mobile data access will develop quickly in the next ten years. Identification of the potential frequency bands offering cheap and trouble-free wireless infrastructure is therefore an important step towards the definition of new air interfaces. LÄS MER
