  • Linealización de resonadores superconductores 

    Padilla Díaz, Alberto (Universitat Politècnica de Catalunya, 2008-07-24)
    Master thesis (pre-Bologna period)
    Open Access
    Los materiales superconductores de alta temperatura (HTS) permiten realizar dispositivos de muy altas prestaciones y dimensiones muy reducidas. Sin embargo, estos materiales presentan un comportamiento no-lineal ...
  • Lossy filter synthesis of L-band planar filters using novel software 

    Padilla Díaz, Alberto; Mateu Mateu, Jordi; Collado Gómez, Juan Carlos; Rocas Cantenys, Eduard; Ernst, Cristoph; Rius Casals, Juan Manuel; Tamayo Palau, José María; O'Callaghan Castellà, Juan Manuel (2011)
    Conference report

    Lossy synthesis techniques are used to synthesize high performance filters using resonators with a finite Q. With these techniques a transmission response of a lossless filter with lowest possible roll-off is obtained, ...
  • Nonlinear distributed model for bulk acoustic wave resonators 

    Collado Gómez, Juan Carlos; Rocas Cantenys, Eduard; Mateu Mateu, Jordi; Padilla Díaz, Alberto; O'Callaghan Castellà, Juan Manuel (2009-12)
    Article
    Open Access
    This work expands the model proposed by Krimtholz, Leedom, and Matthaei (KLM) model to account for the nonlinear effects occurring in acoustic devices due to the nonlinear stiffened elasticity.We show that a nonlinear ...
  • Passive intermodulation due to self-heating in printed transmission lines 

    Rocas Cantenys, Eduard; Collado Gómez, Juan Carlos; Orloff, Nathan; Mateu Mateu, Jordi; Padilla Díaz, Alberto; O'Callaghan Castellà, Juan Manuel; Booth, James C. (2011)
    Article
    Open Access
  • Synthesis of 4th order lossy filters with uniform Q distribution 

    Mateu Mateu, Jordi; Padilla Díaz, Alberto; Collado Gómez, Juan Carlos; Martínez-Mendoza, Mónica; Rocas Cantenys, Eduard; Ernst, Cristoph; O'Callaghan Castellà, Juan Manuel (IEEE Microwave Theory and Techniques Society, 2010)

  • Third-order intermodulation distorsion and harmonic genertion in mismatched weakly nonlinear transmission lines 

    Mateu Mateu, Jordi; Collado Gómez, Juan Carlos; Orloff, Nathan; Booth, James C.; Rocas Cantenys, Eduard; Padilla Díaz, Alberto; O'Callaghan Castellà, Juan Manuel (IEEE, 2009-01)
    Article
    Open Access
    This paper describes a procedure to obtain analytical expressions for the spurious signals generated in nonlinear transmission lines with impedance mismatch when they are subject to small-signals. Using these expressions ...
