  1. 21. Microwave CMOS VCOs and Front-Ends - using integrated passives on-chip and on-carrier

    Författare :Markus Törmänen; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VCO; mixer; microwave; LNA; CMOS; front-end; System-on-Package;

    Sammanfattning : The increasing demand for high data rates in wireless communication systems is increasing the requirements on the transceiver front-ends, as they are pushed to utilize more and wider bands at higher frequencies. The work in this thesis is focused on receiver front-ends composed of Low Noise Amplifiers (LNAs), Mixers, and Voltage Controlled Oscillators (VCOs) operating at microwave frequencies. LÄS MER

  3. 22. Microwave CMOS LNAs and VCOs - Using Passives On-Chip, Above Chip, and Off-Chip

    Författare :Lars Aspemyr; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VCO; LNA; CMOS; Wafer-Level-Packaging; Ferro-electric varactor; System-on-Package;

    Sammanfattning : The performance of LNAs and VCOs is of large importance to the complete wireless communications system. To achieve sufficient performance in microwave applications, LNAs and VCOs have therefore up to now mostly been manufactured in advanced and expensive semiconductor technologies. LÄS MER

  4. 23. Micro- and Millimeter Wave CMOS Beamforming Receivers

    Författare :Andreas Axholt; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; beamforming; CMOS; front-end; microwave; millimeter wave; phase-locked loop; phased-array;

    Sammanfattning : The available bandwidth in wireless communication systems, such as the 802.11 family, is very limited. Together with the ever increasing data traffic, this causes problems. New possibilities are, however, available thanks to wide license-free bandwidth allocated at higher frequencies. LÄS MER

  5. 24. Josephson Junctions: Oscillators and Broadband Spectrometers at Frequencies up to 1 THz

    Författare :Jonas Edstam; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis is devoted to some selected applications of the Josephson junction oscillator. The initial work was performed using low-Tc Nb/PbBi tunnel junctions, while the later parts were done using the recently developed high-Tc YBa2Cu3O7 (YBCO) Josephson junctions. LÄS MER

  7. 25. An SBU fully additive production approach for Board-level Electronics Packaging (SBU-CBM Method)

    Författare :Sarthak Acharya; Jerker Delsing; Shailesh Singh Chouhan; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cyberfysiska system; Cyber-Physical Systems;

    Sammanfattning : The worldwide electronics market is focusing on developing innovative technologies that can lead to denser, more resilient, and tighter board-level integration. The consumer electronics market is trending toward miniaturization, with HDI-PCBs dominating. Electronics shrinking and scaling technology is the prime concern of all manufacturers. LÄS MER
