    Sammanfattning : Hydrogen has been identified by the European Commission to be a competitive alternative to fossil fuels within the transport sector in the medium to long perspective. Because of this, an increased understanding is required of the electrical power train present within such vehicles. LÄS MER

  4. 3. E-Band SPDT RF Switch for a Class F PA in III-V Nanowire MOSFET Technology

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Rungeng Xu; [2022]
    Nyckelord :E-band; III-V Nanowire MOSFET; RF Switch; Class-F PA; Technology and Engineering;

    Sammanfattning : This project designs an RF switch operating in E-band to provide a transmit path from a Class-F power amplifier (PA). The basic RF switch is based on the single-pole double-throw (SPDT) topology using shunt transistor switches and two λ/4 transmission line. LÄS MER

  5. 4. Investigating power amplifier behavior in User Equipment terminals

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Adyasha Panda; [2021]
    Nyckelord :Power Amplifier; Technology and Engineering;

    Sammanfattning : In this thesis work, experiments have been carried out to study the behavior of radio frequency power amplifier which is the one of the largest power consumers in a user equipment which is a mobile phone in this case. A CMW-500 which is a Rohde and Schwarz equipment has been used to emulate the base station. LÄS MER
