  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

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

    Author : Gustav Eliasson; [2023]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 2. Electrical Impedance Profiling of Plants, Coffee and TREO

    University essay from Uppsala universitet/Signaler och system

    Author : Adam Bushara; Sebastian Daniel Clyne; [2022]
    Keywords : ;

    Abstract :  The aim of the project was to investigate the possibility of using low-cost hardware to monitor plant health, measure the impedance of water containing dissolved substances at different concentrations, and observe how the plant impedance is affected compared to auxiliary measurements of soil moisture, ambient light, humidity, and temperature.To measure impedance, we used electrical impedance spectroscopy which gives the impedanceacross a spectrum of frequencies.

  4. 3. Implementation of Spectrum Analysis Functionality for IQ-Signal.

    University essay from Högskolan i Gävle/Avdelningen för elektroteknik, matematik och naturvetenskap

    Author : Gedion Biredaw Anbessa; [2020]
    Keywords : RF Measurement Techniques; Spectrum Analyzer; Synthetic Spectrum Analysis; Synthetic Instrument; Signal Processing; Vector Signal Analyzer; IQ-signal;

    Abstract : The spectrum analyzer is a standard tool used to measure signals in the frequency domain. Traditional spectrum analyzers are based on sweeping a local oscillator and using this to mix signals down to an intermediate frequency (IF) and, subsequently filter them with a filter of settable characteristics, called the Resolution Bandwidth (RBW).

  5. 4. Field uniformity and isotropy investigation of Halmstad University's reverberation chamber : In collaboration with Halmstad University and Ericsson AB, Lund

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Khaled Ads; [2020]
    Keywords : Reverberation chamber;

    Abstract : This thesis is the final module of the Master's program in Electronics Design at Halmstad University. The Master Thesis work is a part of an ongoing development of Halmstad University's reverberation chamber (RC), which is aimed at frequencies in the low GHz range. The development process has been passing in several phases. READ MORE

  6. 5. Near-Field Measurement System for 5G Advanced Antenna System at mm-Wavelength

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

    Author : Bofei Wang; [2020]
    Keywords : Near-field; Measurement system; 5G; mm-wave length; antenna; Technology and Engineering;

    Abstract : An antenna is one of the most fundamental elements of wireless communication systems. The radiation behavior of antennas is characterized with the aid of the farfield radiation pattern. In this thesis, a near-field antenna measurement system is designed to predict the far-field pattern of antenna operational frequency 28 GHz and 39 GHz. READ MORE
