    • Characterization and modeling of the conducted emission of integrated circuits up to 3 GHz 

      Berbel Artal, Néstor; Fernández García, Raúl; Gil Galí, Ignacio (2014-08-01)
      Article
      Accés restringit per política de l'editorial
      In this paper, an electrical model in order to predict the electromagnetic compatibility (EMC) conducted emission of integrated circuits (ICs) up to 3 GHz is presented. The electrical model predicts the behavior of the ...

    • Circuit model for mode conversion in coplanar waveguide asymmetric series-impedances 

      Ribó i Pal, Miquel; Cruz Llopis, Luis Javier de la; Pradell i Cara, Lluís (IEE-INST ELEC ENG, 1999-10-31)
      Article
      Accés obert
      A new `circuit model' for converting between even and odd modes in asymmetric series impedances in the ground plane of a coplanar waveguide is presented. The model is based on the separation of modes into two input and two ...

    • Dual-band planar quadrature hybrid with enhanced bandwidth response 

      Collado Gómez, Juan Carlos; Grau Besolí, Alfred; Flaviis, Franco de (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2006-01-31)
      Article
      Accés obert
      This paper presents the theory, design procedure, and implementation of a dual-band planar quadrature hybrid with enhanced bandwidth. The topology of the circuit is a three-branch-line (3-BL) quadrature hybrid, which ...

    • Exploiting dimensionality and defect mitigation to create tunable microwave dielectrics 

      Lee, Che-Hui; Orloff, Nathan D.; Birol, Turan; Rocas Cantenys, Eduard (2013-10)
      Article
      Accés restringit per política de l'editorial
      The miniaturization and integration of frequency-agile microwave circuits-relevant to electronically tunable filters, antennas, resonators and phase shifters-with microelectronics offers tantalizing device possibilities, ...

    • FSSCat: The Federated Satellite Systems 3Cat Mission: Demonstrating the capabilities of CubeSats to monitor essential climate variables of the water cycle
