3. 27. Characterization of Passive Intermodulation Distortion in MultiBand FDD Radio Systems

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Tomás Soares da Costa; [2019]
   Keywords : ;

   Abstract : Intermodulation distortion (IMD) is a phenomenon that results in generation of spurious distortion signals when two or more signals of different frequencies pass through a nonlinear system. In general, IMD occurs in active circuits of a radio system, however, passive wireless components such as filters, transmission lines, connectors, antennas, attenuators etc. READ MORE
