  5. 3. Analytical Approaches to Load Modulation Power Amplifier Design

    Author : William Hallberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; linear; load modulated balanced amplifier LMBA ; Active load-pull; radio frequency RF ; Wilkinson power divider.; load modulation; energy efficiency; microwave; power amplifier PA ; Doherty;

    Abstract : In future mobile communication networks, there will be a shift toward higher carrier frequencies and highly integrated multiple antenna systems. The system performance will largely depend on the available radio frequency (RF) hardware. As such, RF power amplifiers (PAs) with improved performance, e.g. READ MORE

  6. 4. Improving the functionality of synchronous machines using power electronics

    Author : Fredrik Evestedt; Urban Lundin; C. Johan. D. Abrahamsson; Jon Kjellin; Uppsala universitet; []
