  1. 1. D-band Power Amplifiers in Vertical InGaAs Nanowire MOSFET Technology for 100 Gbps Wireless Communication

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Patrik Blomberg; Ludvig Pile; [2022]
    Keywords : D-band; Power Amplifier; Pseudo-differential common source; Stacked; Vertical InGaAs nanowire; MOSFET; Technology and Engineering;

    Abstract : Two different topologies of power amplifiers (PAs) are designed in the frequency range 130-174.8 GHz for use in backhaul transmitters. These are the pseudo-differential common source (PDCS) and the single-ended stacked amplifier topologies. READ MORE

  2. 2. Design of Two 28 GHz Doherty Power Amplifier Topologies with Vertical In(Ga)As Nanowire Transistors

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Simon Olson; Lucas Nilsson-Villoresi; [2020]
    Keywords : Doherty; PA; DPA; 28 GHz; Power amplifier; nanowire; transistor; In Ga As; Technology and Engineering;

    Abstract : In this Master’s thesis, two different 28 GHz Doherty power amplifiers (DPAs) are designed, for high power added efficiency (PAE), in the common source (CS) and cascoded topology respectively. The results are analyzed and compared between the two approaches. READ MORE

  3. 3. Graph Neural Networks and Learned Approximate Message Passing Algorithms for Massive MIMO Detection

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Andrea Scotti; [2020]
    Keywords : ;

    Abstract : Massive multiple-input and multiple-output (MIMO) is a method to improvethe performance of wireless communication systems by having a large numberof antennas at both the transmitter and the receiver. In the fifth-generation(5G) mobile communication system, Massive MIMO is a key technology toface the increasing number of mobile users and satisfy user demands. READ MORE
