3. 2. 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

4. 3. Quai-Passive 5.8 GHz Front-End Design and Implementation for Vital Signs Detection

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

   Författare :Henrik Kalvér; [2018]
   Nyckelord :;

   Sammanfattning : This thesis investigates the possibility to measure vital signs, such as heartbeat and respiratory rate, by developing a RF-front end for wireless detection. The RF-front has been developed and manufactured as a continuous wave Doppler radar receiver, which utilizes quadrature demodulation by means of a multi-port correlator together with power detectors for down conversion.
