  1. 1. Software Defined VNA : Measure Coupling Between Elements in an Antenna Array

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Alexander Söderlund; [2023]
    Nyckelord :VNA; Vector Network Analyser; SDR; KrakenSDR; S-parameter; Antenna Coupling;

    Sammanfattning : With improvements in hardware of antenna receivers, fully digital arrays have been made possible to use in real time systems. These systems have a greater complexity, with the advantage of more dynamic system design since the use of the communication system can be changed with only a software change. LÄS MER

  3. 2. Verification of Third Party Components to The Road Telematics Communicator

    Master-uppsats, Blekinge Tekniska Högskola

    Författare :Shanmukha Raju Mantena; [2020]
    Nyckelord :Telematics; Global positioning system; Vector signal generator; Signal analyzer; RF Communication; Signal processing; Quality assurance;

    Sammanfattning : The Road Telematics Communicator (RTC) as it is called in Scania. It is the device responsible to keep the vehicle connected and send the vehicle data to the off-board system. It uses data from different sources such as GNSS signals, CAN signal, and wireless Telecom signals. LÄS MER

  4. 3. Design of a sharp response low-pass filter : through comparison of microwave design software

    Master-uppsats, Avdelningen för elektronik, matematik och naturvetenskap

    Författare :Juan Pedro Sánchez Ripoll; [2012]
    Nyckelord :filter; design; software;

    Sammanfattning : The aim of this thesis is to do a research about three microwave design software packages and evaluate them with the purpose of getting the sharpest filter as possible and also know which one is more efficient in this task. In order to achieve this purpose we designed, simulated and tried to manufacture the same low-pass filter (using microstrip lines) in different software. LÄS MER

  5. 4. Multidimensional Measurements : on RF Power Amplifiers

    Magister-uppsats, Institutionen för teknik och byggd miljö

    Författare :Hibah Al-Tahir; [2008]
    Nyckelord :automated multidimentional measurments; RF; power amplifiers; time domain measurements; Gain; efficiency; distortion; three dimensional plots; power sweep; frequency sweep;

    Sammanfattning : Abstract In this thesis, a measurement system was set to perform comprehensive measurements on RF power amplifiers. Data obtained from the measurements is then processed mathematically to obtain three dimensional graphs of the basic parameters affected or generated by nonlinearities of the amplifier i.e. gain, efficiency and distortion.

  7. 5. Network Analyzer Functionality Simulator

    Magister-uppsats, Institutionen för teknik och byggd miljö

    Författare :Ramón Rodriguez; [2007]
    Nyckelord :RF; VNA; instrumentation;

    Sammanfattning : The objective of this thesis work was to implement all the hardware and software necessary to simulate the functionality of a Vector Network Analyzer (VNA). With equipment that is already available, and is common in a measurement station, the most common functions of a VNA were implemented, using an Vector Signal Generator, that provide the signal for testing, and a Vector Signal Analyzer, to make all the amplitude and phase measurements.
