Low-loss 2-bit tunable bandpass filters using MEMS DC contact switches
Arnaud Pothier,Jean-Christophe Orlianges,G. Zheng,Corinne Champeaux,Alain Catherinot,Dominique Cros,Pierre Blondy,John Papapolymerou +7 more
TL;DR: In this article, the authors presented the development of tunable filters using ohmic contact microelectromechanical system switches, which is very well suited for the fabrication of low-loss high tuning-range microwave filters.

MEMS switchable interdigital coplanar filter
Erwan Fourn,Arnaud Pothier,Corinne Champeaux,Pascal Tristant,Alain Catherinot,Pierre Blondy,Gérard Tanné,Eric Rius,Christian Person,Fabrice Huret +9 more
TL;DR: In this paper, a tunable interdigital coplanar filter with tapped-line feedings is presented, where capacitors are used as a high contrast capacitive switch between a quarter-wavelength resonator and an open-ended stub to perform the frequency shift.

Charging in Dielectricless Capacitive RF-MEMS Switches
TL;DR: In this article, the authors present results on high lifetime RF microelectromechanical (RF-MEMS) dielectricless capacitive switches with a capacitance ratio of 9, associated with small residual charging.

Erwan Fourn,Cédric Quendo,Eric Rius,Arnaud Pothier,Pierre Blondy,Corinne Champeaux,Jean-Christophe Orlianges,Alain Catherinot,Gérard Tanné,C. Person,Fabrice Huret +10 more
- 08 Jun 2003
TL;DR: In this paper, a tunable bandpass filter topology is presented, which is based on dual behavior resonators (DBRs), each of which consists of low and high-frequency open-ended stubs.
