1. Analytical Approaches to Load Modulation Power Amplifier Design
Sammanfattning : In future mobile communication networks, there will be a shift toward higher carrier frequencies and highly integrated multiple antenna systems. The system performance will largely depend on the available radio frequency (RF) hardware. As such, RF power amplifiers (PAs) with improved performance, e.g. LÄS MER
2. Efficient and Wideband Load Modulated Power Amplifiers for Wireless Communication
Sammanfattning : The increasing demand for mobile data traffic has resulted in new challenges and requirements for the development of the wireless communication infrastructure. With the transition to higher frequencies and multi-antenna systems, radio frequency (RF) hardware performance, especially the power amplifier (PA), becomes increasingly important. LÄS MER
3. SiC Varactors for Dynamic Load Modulation of Microwave Power Amplifiers
Sammanfattning : The rapid consumer adoption of mobile services is leading to an exponential growth in wireless data traffic. In order to accommodate more concurrent high data-rate users, the required complexity of transmitting radio base station (RBS) power amplifiers (PAs) is increasing. LÄS MER
4. InAs Nanowire Devices and Circuits
Sammanfattning : Since the introduction of the transistor and the integrated circuit, the semiconductor industry has developed at a remarkable pace. By continuously fabricating smaller and faster transistors, it has been possible to maintain an exponential increase in performance, a phenomenon famously described by Moore’s Law. LÄS MER
5. A Novel Bone Conduction Implant System
Sammanfattning : Bone conduction is the process by which an acoustic signal vibrates the skull bones to stimulate the cochlea. Patients with pure conductive hearing loss, mixed hearing loss, and single sided deafness are sometimes poorly rehabilitated by conventional air conduction hearing aids due to for example the functionality losses in the middle ear.
