1. RF Compressor (SLED) Phase-Modulation to Reduce Peak Fields in the MAX IV Linear Accelerator
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : Modern particle accelerators need strong electric fields in order to produce high energy particles. Such high voltages are typically reached by injecting pulsed radio frequency power through several steps of amplification. At the end, pulse compression is used to further improve the energy gain at the cost of pulse-length. READ MORE

2. A Quadrature Frequency Generation Chain for Direct-conversion Phased-array 5G Transceivers
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : The 5th generation (5G) has recently specified a new spectrum range, FR2- 5G New Radio (5G-NR), to provide higher spectral efficiency and channel capacity for ubiquitous cellular connectivity where the user ends can be in various types such as picocell stations, sensor nodes, cloud servers, hand-held devices, and so on. Due to the advantage of phased array antennas in performing beam-forming, and improving SNR at higher spectra, multi-antenna systems have gained an inevitable role in developing such radios.

4. Theory of super power saving circuits and configurations for mixed signal CPU for smartcard application
University essay from Institutionen för systemteknikAbstract : Designing an application specific integrated circuit (ASIC) must be starting with careful preparations, otherwise the chip will not be as good as possible. The theoretical studies must cover everything from the chip circuits to the application structure. READ MORE
