  1. 1. Design and characterization of a radio receiver for satellite communication

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Emil Ollars; [2021]
    Keywords : RFFE; RF; ADC; PSK;

    Abstract : Due to the increase in volume and speed of data transmissions in recent years, the demand for high-speed satellite communication solutions has increased. This thesis investigates the possibility of making a receiver for satellite radio based on an Analog Devices ADC evaluation board. READ MORE

  3. 2. 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).

  4. 3. Design and Implementation of a 5.8 GHz superheterodyne FM Video Receiver

    University essay from Linköpings universitet/Fysik och elektroteknik; Linköpings universitet/Tekniska fakulteten

    Author : Carl-Johan Stålberg; [2019]
    Keywords : Superheterodyne Receiver; 5.8 GHz; FM;

    Abstract : This master thesis presents the design and implementation of a super heterodyne 5.8 GHz receiver system for wireless transmission of phase alternating line (PAL) composite video signals. The system is implemented using surface and hole mounted devices on four separate printed circuit board (PCB) stages. These stages include a 5. READ MORE

  5. 4. Digitally Controlled Oscillator for mm-Wave Frequencies

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

    Author : Rikard Gannedahl; Johan Holmstedt; [2018]
    Keywords : RF; RFIC; oscillator; DCO; mm-wave; Technology and Engineering;

    Abstract : In the fifth generation of mobile communication, 5G, frequencies above 30 GHz, so-called millimeter-wave (mm-wave) frequencies are expected to play a prominent role. For the synthesis of these frequencies, the all-digital phase locked loop (ADPLL) has recently gained much attention. READ MORE

  6. 5. System Level Modeling and Verification of All-digital Phase-locked Loop

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Chi Zhang; [2015]
    Keywords : ;

    Abstract : In wirelesscommunication systems, a local oscillator (LO) aims at demodulating radio-frequency signals into baseband signals. The performance of these signals determines the quality of communications which is highly affected by the phase accuracy of local oscillators. READ MORE
