1. Microwave and millimeter wave CMOS Characterization, modeling, and design
Sammanfattning : The use of CMOS technologies for microwave and millimeter wave applications has recently been made possible as a result of increased transistor performance. The fT and fmax have, for example, passed 100 GHz at the 130 nm node and 200 GHz at the 65 nm node. LÄS MER
2. Nonlinear Characterisation and Modelling of Microwave Semiconductor Devices
Sammanfattning : There is an increasing need for more accurate models taking into account the nonlinearities and memory effects of microwave transistors. The memory effects are especially important for transistor technologies suffering from relatively large low frequency dispersion, such as GaN baed HEMTs. LÄS MER
3. Nonlinear Microwave Measurement Architectures for Wideband Device Characterization
Sammanfattning : The global surge for ubiquitous mobile communication requiring high speed and high capacity cellular networks has resulted in a golden age for the development of wireless technology. Modern cellular standards employ complex modulation formats with wider signal bandwidths to cope with the growing demand. LÄS MER
4. 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
5. 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
