    Sammanfattning : Advancements in photonic integrated circuits, so-called PICs, have progressed fast in the last decades. More complex PICs are getting developed, which are promising in possibly offering advantages like low power consumption and high-performance computing. Re-programmable photonic FPGAs are one of these candidates. LÄS MER

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

    Master-uppsats, Linköpings universitet/Fysik och elektroteknik; Linköpings universitet/Tekniska fakulteten

    Författare :Carl-Johan Stålberg; [2019]
    Nyckelord :Superheterodyne Receiver; 5.8 GHz; FM;

    Sammanfattning : 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. LÄS MER

  5. 4. Design of Variable Attenuators Using Different Kinds of PIN-Diodes

    Master-uppsats, Fysik och elektroteknik; Tekniska högskolan

    Författare :Imran Choudhury; [2013]
    Nyckelord :PIN diode; attenuator; variable attenuator; Imran choudhury;

    Sammanfattning : Variable attenuators are important circuits that can be employed in many radio frequency (RF) applications, e.g., in automatic gain control (AGC) amplifiers, broadband gain-control blocks at RF frequencies or as broadband vector modulators. For any applications, low insertion phase shift and low power consumption are of interest. LÄS MER

  7. 5. Analys och förbättringsförslag för riktkopplardesign

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Alexander Regamey; [2005]
    Nyckelord :directional coupler; design of a directional coupler; stripline; microstrip; UMTS; riktkopplare; riktkopplardesign; stripline; mikrostrip; UMTS;

    Sammanfattning : Ericsson develops a new stripline directional coupler. Its design is described in appendix B and differs from the directional couplers Ericsson uses in current products. The new directional coupler will be used for transmission power measurement in future UMTS 3G base stations. The most important parts of directional coupler theory are presented. LÄS MER
