  • 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
    Restricted access - publisher's policy
    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)
    Article

    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 ...
  • 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 ...
  • Exploiting dimensionality and defect mitigation to create tunable microwave dielectrics 

    Lee, Che-Hui; Orloff, Nathan D.; Birol, Turan; Rocas Cantenys, Eduard (2013-10)
    Article
    Restricted access - publisher's policy
    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, ...
  • 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 ...

  • Sources of third–order intermodulation distortion in bulk acoustic wave devices: a phenomenological approach 

    Rocas Cantenys, Eduard; Collado Gómez, Juan Carlos (In-Teh (www.intechweb.org), 2011)
    Part of book or chapter of book
    Open Access
    In this work, a model that uses several nonlinear parameters to predict harmonics and 3IMD distortion is presented. Its novelty lies in its ability to predict the nonlinear effects produced by self-heating in addition to ...
  • 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)
