  1. 1. Performance of 2-18 GHz RF Switches Implemented in Chip & Wire Technology : Analysis of switch topologies, bias networks and an in-depth EM analysis of bondwires

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

    Författare :Gustav Eliasson; [2023]
    Nyckelord :RF Switch; PIN diode; Chip Wire Technology; Wide Bandwidth; High isolation; Single-Pole-Single-Throw; Single-Pole-Double-Throw RF Switch; PIN diode; Chip Wire Technology; Wide Bandwidth; Single-Pole-SingleThrow; Single-Pole-Double-Throw; RF-omkopplare; PIN-diod; Chip Wire Tekonologi; Bredbandig; Hög isolation; Enkelpolig-enkakast; Enkelpolig-dubbelkast;

    Sammanfattning : The ability to control the path a signal takes through microwave circuitry is crucial when designing RF systems. The component that allows for the control of the signal path is called a switch, and it is the microwave component that this thesis will focus on. LÄS MER

  3. 2. Analysis and Measurement of Key Performance Indicators for MIMO Antennas

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Ossian Kynman; [2023]
    Nyckelord :MIMO; Diversity Gain; Capacity; Correlation; Fading;

    Sammanfattning : Multiple-in multiple-out (MIMO) is a wireless communication technique where antenna arrays, at the receiver and transmitter, utilize signal multipath propagation to increase data throughput capacity. The unique benefits MIMO provides have over the last 20 years led to the steady increase in usage in both Wi-Fi and mobile networks. LÄS MER

  4. 3. Dataset based on volunteer campaign to optimize novel sensor for muscle quality

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Fasta tillståndets elektronik

    Författare :Sophia Holmqvist; [2022]
    Nyckelord :sarcopenia; microwaves; medical imaging;

    Sammanfattning : This project had its primary focus on running a campaign to recruit healthy volunteers for a test study involving the utilization of a microwave sensor and ultrasound measurements. The key system used was the Muscle Analyzer System (MAS), which consisted of the Bandstop Filter Sensor (BFS), a microwave sensor transmitting microwaves into the selected medium through transmission and a FieldFox Vector Network Analyzer which was used to transmit these microwaves.

  5. 4. Graphene-based Crack-Free Ceramic Coatings for High-Performance Passive RF Devices

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

    Författare :Haomin Liu; [2021]
    Nyckelord :;

    Sammanfattning : Dielectric resonators coated with highly conductive metallic layers are widely used in radio frequency (RF) applications. The quality factor (Q-factor) of resonators is a key figure-of-merit that describes the loss and the energy efficiency of the resonators. LÄS MER

  7. 5. Analysis of RISE's VIRC for Automotive EMC Immunity Testing

    Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

    Författare :Andreas Lundberg; [2021]
    Nyckelord :Electromagnetic Compatibility EMC ; Reverberation Chamber RC ; Vibrating Intrinsic Reverberation Chamber VIRC ; Cumulative Distribution Function CDF ; Rayleigh Distribution; Vector Network Analyzer VNA ; Immunity testing;

    Sammanfattning : RCs (Reverberation Chambers) has historically been used mainly for aerospace and military purposes in EMC (Electromagnetic Compatibility) testing, but the interest also seems to increase in the automotive industry (the development of an international standard for vehicles is in progress). The vehicles of the future will most likely be electrified, wirelessly connected and autonomous, i. LÄS MER
