  • 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 ...
  • 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. ...
  • K-band RF-MEMS uniplanar reconfigurable-bandwidth bandpass filter using multimodal immittance inverters 

    Contreras Lizarraga, Adrián Arturo; Ribó i Pal, Miquel; Pradell i Cara, Lluís; Casals Terré, Jasmina; Giacomozzi, Flavio; Iannacci, Jacopo (Institution of Electrical Engineers, 2013-05-23)
    Article
    Restricted access - publisher's policy
    A K-band RF-MEMS uniplanar second-order bandpass filter with reconfigurable bandwidth is presented. The filter is based on inductively-coupled half-wavelength slotline resonators and CPW-slotline multimodal immittance ...
  • 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
