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)
Comunicación de congreso
Acceso abiertoThis 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 ... -

Acceso restringido por política de la editorialIn 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)
Texto en actas de congreso
Acceso abiertoThis 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)
Texto en actas de congreso
Acceso restringido por política de la editorialIn 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 ... -

Texto en actas de congreso
Acceso restringido por política de la editorialIn 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)
Texto en actas de congreso
Acceso restringido por política de la editorialThis 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 ...
