  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. 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.

  4. 3. Phase shifter design & Research study and verification of wideband phase shifter circuits

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : JAYAPRAKASH SELVARAJ; [2012]
    Keywords : ;

    Abstract : Radio Frequency waves are widely used for the purpose of radio communication. Active research in Radio Frequency technology has led to the use of RF waves in variety of application other than radio communication. Phase shifters are a major functional block in RF transmission circuits. READ MORE

  5. 4. Theory of super power saving circuits and configurations for mixed signal CPU for smartcard application

    University essay from Institutionen för systemteknik

    Author : Anders Kleist; [2004]
    Keywords : Electronics; charge pump; sleep-mode; level shifter; cholesteric; liquid crystal; smartcard; DC-DC converter; MTCMOS; display driving; assembler; voltage doubler; low power; Elektronik;

    Abstract : 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
