1. Transmitter Linearization for mm-Wave Communications Systems
Sammanfattning : There is an ever increasing need for enabling higher data rates in modern communication systems which brings new challenges in terms of the power consumption and nonlinearity of hardware components. These problems become prominent in power amplifiers (PAs) and can significantly degrade the performance of transmitters, and hence the overall communication system. LÄS MER
2. Advanced Analog MMICs for mm-wave Communication and Remote Sensing in 0.15µm mHEMT Technology
Sammanfattning : Multi-Gigabit per second wireless communication and atmospheric remote sensing for weather forecasts are new applications in the mm-wave frequency spectra. The High Electron Mobility Transistor is an excellent technology for high frequency mm-wave applications. Its low noise and linear performance makes a 0. LÄS MER
