  1. 6. Current-Mode Class D Power Amplifier for 2.4GHz Wi-Fi

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Yann Jean Michael Pirot; [2023]
    Nyckelord :Power Amplifier; Wifi; Digital Power Amplfier; Class D; RFIC; Analogue; Effektförstärkare; Wifi; digital förstärkare; klass D; analog;

    Sammanfattning : Modern wireless communication techniques employed in the Wi-Fi® protocol, such as orthogonal frequency-division multiplexing exhibit analogue signals with high peak-to-average power ratio. Therefore, power amplifiers for Wi-Fi suffer from low efficiency when operating in back-off mode, away from their maximum efficiency at peak power. LÄS MER
