  1. 1. 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

  3. 2. Investigating power amplifier behavior in User Equipment terminals

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