  1. 1. Designing of Reconfigurable Multiband Antenna for WLAN Application

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Sarfraz Hussain; Jibran Khan; [2013]
    Nyckelord :Mulitiband; Reconfiguration; Recunfigurable ; Antenna ; Parametric Study;

    Sammanfattning : Remarkable equipment development in the field of communication and the growing end user requirement has lifted the need for multi-functional wireless communication devices. Since antenna is the basic part of each wireless communication scheme and multi-functional antennas are looked-for to meet up the requirements of present progress, those be able to sustain compound functions in a particular antenna constituent by sustaining other than one operational frequency .

  3. 2. Design of a DCO for an All Digital PLL for the 60 GHz Band : Design of a DCO for an All Digital PLL for the 60 GHz Band

    Master-uppsats, Elektroniksystem; Tekniska högskolan

    Författare :Manikandan Balasubramanian; Saravana Prabhu Vijayanathan; [2013]
    Nyckelord :DCO; 65 nm; Oscillator; Varactor; Jitter; Differential to single; All-digital PLL; PLL;

    Sammanfattning : The work was based on digitally controlled oscillator for an all-digital PLL in 65nm process. Phase locked loop’s were used in most of the application for clock generation and recovery as well. As the technology grows faster in the existinggeneration, there has to be quick development with the technique. LÄS MER

  4. 3.  Evaluation of broadband MMIC oscillators with external tank

    Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Anette Brandt; [2010]
    Nyckelord :;

    Sammanfattning : This thesis evaluates broadband Voltage Controlled Oscillators, VCO´s, using different VCO topologies and external tanks. The work has been done at Sivers IMA AB within the "INTOSC" project in the framework of the VINNEX Centre "GHZ CENTRE". Different VCO topologies are investigated and their performance is compared and evaluated. LÄS MER

  5. 4. C Band Microwave Oscillator

    Master-uppsats, Institutionen för teknik och byggd miljö; Högskolan i Gävle

    Författare :Maaz Rasheed; [2008]
    Nyckelord :;

    Sammanfattning : The work focuses on the study, design and implementation of a C band Microwave oscillator using coaxial resonators, for the transceiver used in wave radar. It involves a literature study discussing different aspects of microwave oscillators, mainly the shielding of the oscillators, frequency pulling due to load and supply pulling, tuning range and the temperature performance of the oscillator.
