  • A consistent methodology to characterize BAW resonators 

    Rocas Cantenys, Eduard; Collado Gómez, Juan Carlos; Aigner, Robert; Mateu Mateu, Jordi; Hueltes Escobar, Alberto; Booth, James C. (2012)
    Conference report

    We present a methodology to characterize BAW resonators both linearly and nonlinearly. The procedure uses physical modeling along with measurements that exploit different manifestations of the nonlinear phenomena to ...
  • Absorptive limiter for frequency-selective circuits 

    Collado Gómez, Juan Carlos; Hueltes Escobar, Alberto; Rocas Cantenys, Eduard; Mateu Mateu, Jordi; Booth, James C.; O'Callaghan Castellà, Juan Manuel; Verdú Tirado, Jorge Andrés (2014-06-01)

    This letter describes a novel absorptive limiter for frequency-selective circuits. The proposed circuit allows the design of absorptive limiters based on a bi-state phase shifter, which is appropriate for integration into ...
  • Detuning and saturation of superconducting devices: formulation and measurements 

    Collado Gómez, Juan Carlos; Mateu Mateu, Jordi; Booth, James C.; O'Callaghan Castellà, Juan Manuel (Institute of Electrical and Electronics Engineers, 2007-06)
    Conference report
    Open Access
    Saturation and detuning of high temperature superconducting (HTS) resonators and filters may occur due to the inherent nonlinear properties of the superconductor. In HTS transmission lines, these nonlinear properties ...
  • Electro-thermo-mechanical model for bulk acoustic wave resonators 

    Rocas Cantenys, Eduard; Collado Gómez, Juan Carlos; Mateu Mateu, Jordi; Orloff, Nathan D.; Booth, James C.; Aigner, Robert (2013-11)
    Article
    Restricted access - publisher's policy
    We present the electro-thermo-mechanical constitutive relations, expanded up to the third order, for a BAW resonator. The relations obtained are implemented into a circuit model, which is validated with extensive linear ...
  • Intermodulation distortion in coupled-resonator filters with nonuniformly distributed nonlinear properties - Use in HTS IMD compensation. 

    Mateu Mateu, Jordi; Booth, James C.; Collado Gómez, Juan Carlos; O'Callaghan Castellà, Juan Manuel (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2007-04-30)
    Article
    Open Access
    We present a general procedure for calculating intermodulation distortion in coupled-resonator filters that allows one to predict the performance of a nonlinear filter as a function of the general nodal matrix defining the ...
  • Measurements and analysis of microwave nonlinearities in ferroelectric thin film transmission lines 

    Mateu Mateu, Jordi; Booth, James C.; Schima, S. A.; Collado Gómez, Juan Carlos; Seron, David; O'Callaghan Castellà, Juan Manuel (Institute of Electrical and Electronics Engineers, 2006)
    Conference report
    Open Access
    This work evaluates the microwave nonlinear properties of ferroelectric BaSrTiO thin films by measuring the frequency response of several coplanar transmission lines and interdigital capacitor structures as a function of ...
  • 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

  • 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 ...
