  1. 1. Investigation of Analog Calibration Systems for Spurious Tone Suppression in Frequency Triplers

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

    Author : Cristian Alexandru Ghihanis; Barath Copparam Santhanakrishnan Sudarsan; [2023]
    Keywords : Delay-Locked Loop; DLL; Edge-Combining; EC; EC DLL; Edge-Combining Delay-Locked Loop; spurious tone calibration; spurs calibration; spurious tones compensation; spurs compensation; Technology and Engineering;

    Abstract : The market for Wi-Fi receiver designs for latest Wi-Fi standards, that cover RF bands in the 2.4 GHz, 5 GHz and 6 GHz spectrum, require increasingly stringent power consumption limitations as more of the market is driven towards battery-powered devices. READ MORE

  3. 2. Measurements, Estimations and Calibration with a Fully Digital Array

    University essay from Uppsala universitet/Signaler och system

    Author : Oscar Magnér; [2023]
    Keywords : WiDAR; signal processing; digital array; broadband antenna; array antenna; antenna; calibration; direct sampling; antenn; bredbandig; digital array; array antenn; direktsampling; signalbehandling; kalibrering; WiDAR; Saab AB; SAAB;

    Abstract : In modern digital communication, transmission and reception of information through electromagnetic signals requires digital devices that can process high data rates accurately despite being located in information heavy environments. One type of antenna receiver is the digital antenna array, which can steer its lobes electronically to increase or decrease sensitivity in specific directions. READ MORE

  4. 3. A Study of Direction of Arrival Methods Based on Antenna Arrays in Presence of Model Errors.

    University essay from Uppsala universitet/Signaler och system

    Author : Julia Sjödin; [2022]
    Keywords : Direction of Arrival; DOA; WSF; MUSIC; TLS-ESPRIT; Extended Kalman filter; model error;

    Abstract : Methods for Direction of Arrival, DOA estimation of multiple objects based on phased arrayantenna technology have many advantages in for example electronic warfare and radarapplications. However, perfect calibration of an antenna array can seldom be achieved. READ MORE

  5. 4. LISA’s Phasemeter Structural-Thermal Model test campaign and computational model calibration

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Richard Johansson; [2022]
    Keywords : Richard Johansson; LISA;

    Abstract : This work aims to plan, prepare and perform a test campaign of the Back-End Electronics(BEE) module in the phasemeter instrument on board the Laser Interferometer Space Antenna(LISA). Results from the test are analyzed to thermally characterize the BEE module as wellto evaluate how successfully an aluminum enclosure mounted on the BEE can dissipate heatloads from the BEE.
