    • A RF-MEMS switchable CPW air-bridge 

      Contreras, Adrián; Casals Terré, Jasmina; Pradell i Cara, Lluís; Giacomozzi, Flavio; Colpo, Sabrina; Iannacci, Jacopo; Ribó, Miquel (2012)
      Conference lecture
      Open Access
      This work presents a new shunt-type ohmic contact RF-MEMS switch specifically designed as a switchable CPW air bridge. The switch can be used in coplanar waveguide (CPW) reconfigurable multimodal circuits, for a selective ...

    • Analytical energy model for the dynamic behavior of RF MEMS switches under increased actuation voltage 

      Casals Terré, Jasmina; Llamas, Marco Antonio; Girbau Sala, David; Pradell i Cara, Lluís; Lázaro Guillén, Antonio; Giacomozzi, Flavio; Colpo, Sabrina (2014-12-01)

      Restricted access - publisher's policy
      In this paper, the dynamic behavior of electrostatically actuated radio frequency-microelectromechanical system (RF-MEMS) switches is analyzed using energy considerations. An analytical model for bridge-type RF-MEMS switches ...

    • Conmutadores RF-MEMS de baja tensión 

      Contreras Lizarraga, Adrián Arturo; Casals Terré, Jasmina; Pradell i Cara, Lluís; Colpo, Sabrina; Iannacci, Jacopo; Ribó, Miquel; Giacomozzi, Flavio (2012)
      Conference report
      Open Access
      This work shows experimental results of capacitive and ohmic RF-MEMS switches with low actuation voltage. The isolation of capacitive switches is better than 20 dB from 15 GHz and up to 80 GHz according to simulations. ...

    • Filtro paso-banda con control preciso de frecuencia central y ancho de banda usando interruptores RF MEMS 

      Brito Brito, Zabdiel; Llamas Garro, Ignacio; Perruisseau Carrier, Julien; Pradell i Cara, Lluís; Giacomozzi, Flavio; Colpo, Sabrina (2012)
      Conference report
      Restricted access - publisher's policy
      In this paper a reconfigurable bandpass filter is presented. The filter is able to switch between two different states with a center frequency tunable range of 24 % in C band. Center frequency and bandwidth are precisely ...

    • Frequency and bandwidth control of switchable microstrip bandpass filters using RF-MEMS ohmic switches

      Restricted access - publisher's policy
      In this paper a reconfigurable bandpass filter is designed using ohmic-contact cantilever-type Micro Electro Mechanical Systems (MEMS) switches., Tthe filter can switch between two different states with a center frequency ...

    • Low voltage capacitive and Ohmic RF-MEMS Switches 

      Contreras Lizarraga, Adrián Arturo; Casals Terré, Jasmina; Pradell i Cara, Lluís; Giacomozzi, Flavio; Colpo, Sabrina; Iannacci, Jacopo; Ribó, Miquel (2012)
      Conference report
      Restricted access - publisher's policy
      This work presents experimental results of capacitive and ohmic-contact RF-MEMS switches. The suspension has been designed to compensate stress-gradient effects, and to obtain low pull-in voltages. The measured actuation ...
