1. Class-E Power Amplifiers for Pulsed Transmitters
Sammanfattning : Nowadays the main driving parameters for the radio transmitter research are: energy efficiency, frequency re-configurability and integration. Pulsed transmitter architectures have attracted large interest in the recent years due to their potential to meet these demands. LÄS MER
2. Interference in Global Positioning System Signals and its Effect on Positioning and Remote Sensing
Sammanfattning : GPS and the other GNSS systems (GLONASS, Galileo and Beidou-2/COMPASS) is used to position billions of devices and is saving lives, the environment and money on a daily basis. GNSS enables anyone to determine their own unique global location. LÄS MER
3. Design and Characterization of 1.3-1.6 µm Metamorphic Materials and Lasers on GaAs
Sammanfattning : The development of fiber-optical networks for broad-band access is expected to create a huge market for laser transmitters in the 1.3-1.55 µm wavelength range. The existing InP-based lasers have poor temperature stability. LÄS MER
4. Metamorphic Heterostructures and Lasers on GaAs
Sammanfattning : The objective of this thesis is to demonstrate the metamorphic growth of heterostructure lasers on GaAs substrates. Many heterostructure devices have their performance limited by the need to grow on lattice-matched substrates. LÄS MER
