    A broadband 0º/180º phase switch based on a slotline-coplanar-waveguide cross loaded with two MEMS switches in opposed (ON/OFF or OFF/ON) states, is reported. The fabrication was made on high-resistivity silicon substrates ...
  • A low-power-consumption out-of-Plane electrothermal actuator 

    Girbau Sala, David; Llamas Morote, Marco Antonio; Casals Terré, Jasmina; Simó Selvas, Francisco Javier; Pradell i Cara, Lluís; Lázaro Guillén, Antoni (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2007-06-30)
    Article
    Open Access
    This paper proposes a new vertical electrothermal actuator. It can be considered as a hybrid between the traditional in-plane buckle-beam actuator and the vertical hot-cold actuator. It is here referred to as vertical ...
  • Capacitive and resistive RF-MEMS switches 2.5D & 3D Electromagnetic and Circuit modelling 

    Giacomozzi, Flavio; Colpo, S.; Plana, Robert; Llamas Morote, Marco Antonio; Girbau Sala, David; Pausas, Esther; Pradell i Cara, Lluís; Aouba, Stephane; Villneuve, C.; Puyal, Vincent; Pons, Patrick (2009)
    Conference report
    Open Access
    this paper proposes different strategies for the electrical modelling of capacitive and resistive RF-MEMS switches which take into account the dependence of the electrical performance on the mechanical properties and ...
  • Characterization of dynamics in RF-MEMS switches 

    Llamas Morote, Marco Antonio; Girbau Sala, David; Pradell i Cara, Lluís; Lázaro Guillén, Antoni; Giacomozzi, Flavio; Colpo, S (2009)
    Conference report
    Open Access
    This paper proposes a new method to measure dynamics and power handling of RF microelectromechanical systems (MEMS) devices based on a mobile membrane. The method uses in-phase/quadrature demodulation of an RF signal ...
  • RF-MEMS switches designed for high-performance uniplanar microwave and mm-wave circuits 

    Pradell i Cara, Lluís; Girbau Sala, David; Ribó Pal, Miquel; Casals Terré, Jasmina; Lázaro Guillén, Antonio; Contreras Lizárraga, Adrián; Llamas Morote, Marco Antonio; Heredia Vega, Julio César; Giacomozzi, Flavio; Margesin, Benno (IntechOpen, 2018-07-18)
    Part of book or chapter of book
    Open Access
    Radio frequency microelectromechanical system (RF-MEMS) switches have demonstrated superior electrical performance (lower loss and higher isolation) compared to semiconductor-based devices to implement reconigurable microwave ...
  • RF-MEMS uniplanar 180º Phase Switch based on switching between two out-of-phase paths 

    Llamas Morote, Marco Antonio; Pradell i Cara, Lluís; Girbau Sala, David; Ribó, Miquel; Lázaro Villa, José Antonio; Giacomozzi, Flavio; Margesin, Benno (2011)
    Article
    Restricted access - publisher's policy
    A phase switch based on switching between two twoport passive networks with a phase difference of 180º is reported. Two RF MEMS single-pole-double-throw structures are used to select the phase path. The fabrication is ...
  • RF-MEMS uniplanar 180° phase switch based on a multimodal air-bridged CPW cross
