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

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

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

    Sammanfattning : 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. LÄS MER

  3. 2. Integrated antenna switch for NB-IoT

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

    Författare :Fredrik Zetterblom; Yunus Dawji; [2018]
    Nyckelord :T R Transmit Receive switch; RF switch; integrated RF switch; Narrowband Internet of Things NB-IoT ; CMOS; frontend; Technology and Engineering;

    Sammanfattning : Transistors are used in all digital devices today. The demand of faster and smaller devices such as mobile telephones and computers constantly drives the develop- ment of smaller transistor technologies. Transistors can also be used in analog applications. Today there are commercial chips with both radio and digital sys- tems in the same package. LÄS MER

  4. 3. Design of a Low-Noise Amplifier for Radar Application in the 5 GHz Frequency Band

    Master-uppsats, Högskolan i Gävle/Elektronik

    Författare :Javier Alvaro Rivera Suaña; [2017]
    Nyckelord :;

    Sammanfattning : The purpose of this project was to design and manufacture a Low-Noise Amplifier (LNA) working at a 5 GHz frequency band, by using High Electron Mobility Transistor (HEMT) from Avago Technologies. To improve our design, it was necessary to build a two-stage amplifier; one stage to work in minimum noise sensitivity, and another stage to get the maximum gain achievable by the transistor.

  5. 4. Fabrication, Characterization and Simulation of Graphene Field Effect Transistors operating at Microwave Frequencies

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Pandey Himadri; [2013]
    Nyckelord :Graphene field effect transistor; microwave frequencies; transit frequency;

    Sammanfattning : With the end of Si based Metal Oxide Semiconductor Field Effect Transistor scaling paradigm approaching fast as predicted by the Moore’s Law, and the technological advancements as well as human needs in many ways pushing for faster devices, graphene has emerged as a powerful alternative solution. This is so because of its very special properties like high charge carrier mobility, highly linear dispersion relation, high current carrying capacity and so on. LÄS MER

  7. 5. Development of a wideband high power amplifier for cancer treatment.

    Master-uppsats, Avdelningen för elektronik, matematik och naturvetenskap

    Författare :Sohil Shahabi Ghahfarokhi; [2013]
    Nyckelord :wideband; high power; amplifier; hyperthermia;

    Sammanfattning : Medical hyperthermia refers to heating of tumors to temperature levels which are lethal to the cells for sufficient periods of time or rendering the cancerous cells more sensitive to ionizing radiation or chemotherapy. In order to increase the temperature in cancerous tissues, high power solid state microwave amplifiers need to be used. LÄS MER
