  4. 4. Dynamic load modulation

    Magister-uppsats, Högskolan i Gävle/Institutionen för teknik och byggd miljö

    Författare :Björn Almgren; [2007]
    Nyckelord :load modulation; load tracking; power added efficiency; high efficiency; PA; power amplifier; switch mode; switching; dlm; lm; et; envelope tracking; modulation; load; efficiency; PAE;

    Sammanfattning : The purpose of this master thesis was to study if the drain efficiency of power amplifiers can be maintained at power back off using a technique called load modulation. The amplifier classes studied are E, F and D-1. The target figure was to obtain a 10 to 12 dB dynamic range of amplitude with reasonable efficiency. LÄS MER
