  • Circuit model for coplanar-slotline tees 

    Ribó i Pal, Miquel; Pradell i Cara, Lluís (2000-05)
    Article
    Accés obert
    Coplanar-slotline tees have been used in a number of microwave circuits, although no complete models were available to explain their behavior. In this letter, a new

  • Generalized transverse resonance analysis of planar discontinuities considering the edge effect 

    Barlabe Dalmau, Antoni; Comerón Tejero, Adolfo; Pradell i Cara, Lluís (2000-12)
    Article
    Accés obert
    Abstract: Mode-matching related techniques such as the Generalized Transverse Resonance Method (GTR) suffer from the relative convergence phenomenon. To reduce its influence, we present a technique consisting of the ...
  • Circuit model for mode conversion in coplanar waveguide assymmetric shunt impedances 

    Miquel, Ribó; Pradell i Cara, Lluís (Institution of Electrical Engineers, 1999-04)
    Article
    Accés obert
    A new 'circuit model' for the conversion between even and odd modes in coplanar waveguide asymmetric shunt impedances is presented. The model is based on the separation of modes into two input and two output ports. In ...
  • Numerical optimization of hybrid dielectric/HTS resonators for surface impedance evaluation of HTS films 

    Collado Gómez, Juan Carlos; Gonzalo, David; Rozan, Edouard; O'Callaghan Castellà, Juan Manuel; Sans, C (1999-06)
    Article
    Accés obert
    This work describes an alternative to the traditional dielectric resonator topology used for measuring surface impedance in high temperature superconducting (HTS) films. A gap is introduced above the dielectric so that ...
  • Circuit model for slotline-to-coplanar waveguide asymmetrical transitions 

    Ribó i Pal, Miquel; Cruz, J De La; Pradell i Cara, Lluís (Institution of Electrical Engineers, 1999-07)
    Article
    Accés obert
    A new 'circuit-model' for slotline-to-coplanar waveguide asymmetrical transitions is presented and applied to the design of slotline resonators. The model, based on the separation of coplanar-waveguide (CPW) modes into two ...

  • Extraction of noise parameters of transistor using a spectrum analyser and 50 /spl Theta/ noise figure measurements only 

    Lázaro Guillén, Antoni; Pradell i Cara, Lluís (Institution of Electrical Engineers, 1998-11)
    Article
    Accés obert
    A method for measuring the four noise parameters of a transistor in the microwave range using a configuration based on a conventional spectrum analyser is presented. In contrast to previous methods, it requires wideband ...
