    This paper presents a novel filter configuration based on acoustic wave resonators that allows to obtain filter responses unachievable with the well established ladder configuration, such as arbitrary position of transmission ...
  • A lateral modes model for BAW resonators 

    Collado Gómez, Juan Carlos; Rocas Cantenys, Eduard; Verdú, Jordi; Mateu Mateu, Jordi; Hueltes Escobar, Alberto; Aigner, Robert (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report

    An equivalent circuit model to predict lateral modes occurring in real BAW resonators is proposed. The circuit model has been validated with FEM simulations of FBAR resonators and also with measurements of SMR resonators. ...
  • 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 ...
  • Fast procedure for the nonlinear analysis of BAW resonators 

    Perea Robles, Rafael; García Pastor, David; Mateu Mateu, Jordi; Collado Gómez, Juan Carlos; Aigner, Robert (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference lecture
