19. Design of Multiplexed LO Single Mixer Receiver Front-End
University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)Abstract : A new quadrature receiver architecture is studied and designed in this thesis. In conventional quadrature receivers each of I and Q channels are downconverted separately using a mixer and a local oscillator (LO) in each path. On the other hand, the proposed architecture is based on multiplexed LO signals. READ MORE
