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

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

   Author : Henrik Kalvér; [2018]
   Keywords : ;

   Abstract : 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.
