  1. 1. 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).

  2. 2. Millimeter Wave Antenna Array Calibration and Validation for 5G New Radio Access

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

    Author : Manuel Jose Lopez Morales; [2018]
    Keywords : Technology and Engineering;

    Abstract : This Master thesis work was performed in Ericsson AB, Lund. It studies and validates two classes of algorithms to be used in mm-wave massive MIMO antenna arrays, for their use in the future 5G mobile communication systems. READ MORE

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

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

    Author : Juan Pedro Sánchez Ripoll; [2012]
    Keywords : filter; design; software;

    Abstract : 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. READ MORE

  4. 4. Studying Noise Contributions in Nonlinear Vector Network Analyzer (NVNA) Measurements

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

    Author : Tianyang Feng; [2012]
    Keywords : nonlinear measurements; nonlinear vector network analyzer NVNA ; power amplifier; nonlinear systems; noise contributions.;

    Abstract : Noise contribution in nonlinear systems is very different from that in linear systems. The noise effects in nonlinear systems can be complicated and not obvious to predict. In this thesis, the focus was on the noise contribution in nonlinear systems when measuring with the nonlinear vector network analyzer (NVNA). READ MORE

  5. 5. Characterize the ZGST test bed

    University essay from Högskolan i Gävle/Akademin för teknik och miljö

    Author : zhiyang zhao; [2011]
    Keywords : ;

    Abstract : Nyquist Shannon theory states that sampling rate of ADC should be at least twice of signal bandwidth in order to avoid aliasing. According to this theory, extracting an accurate behavior model of power amplifier by digitizing its output signal is a difficult task for current general ADC in the market, due to the trade off among the sampling rate, resolution and reasonable cost.
