  1. 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 informationsteknik

    Author : Joel Ekström; [2023]
    Keywords : Accelerator; MAX IV; LINAC; Phase-modulation; SLED; Pulse compression; Technology and Engineering;

    Abstract : 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

  3. 2. Microeletromechanical Systems for Tunable Ring Resonators on a Silicon Platform

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Chris Phong Van Nguyen; [2021]
    Keywords : Integrated photonics; Silicon Photonics; MEMS; Silicon Photonic MEMS; Ring Resonator; Telecommunications; Integrerad fotonik; Silicon Photonics; MEMS; Silicon Photonic MEMS; Ringresonator; Telekommunikation;

    Abstract : Advancements in photonic integrated circuits, so-called PICs, have progressed fast in the last decades. More complex PICs are getting developed, which are promising in possibly offering advantages like low power consumption and high-performance computing. Re-programmable photonic FPGAs are one of these candidates. READ MORE

  4. 3. Electrically Steerable Phased-Arrays for 5G Sub-6 GHzMassive MIMO Active Antenna Units : Re-configurable Feed Networks

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Johan Kövamees; [2020]
    Keywords : Electrically Steerable Phased-Arrays for 5G Sub-6 GHz Massive MIMO Active Antenna Units;

    Abstract : During this project we have designed a new type of antenna that uses an array of antenna elements in order to emit electromagnetic radiation as signals and to be able to control the beam. After an extended time the design yielded a simulation which had the correct characteristics. READ MORE

  5. 4. A Quadrature Frequency Generation Chain for Direct-conversion Phased-array 5G Transceivers

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Hamid Yadegar Amin; [2020]
    Keywords : 5G Phased array mm-wave FR2; Technology and Engineering;

    Abstract : 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.
