Innovative RF MEMS switches on GaAs

2010 14th International Symposium on Antenna Technology and Applied Electromagnetics & the American Electromagnetics Conference, 2010
RF-MEMS is an emerging area of MEMS technology that is revolutionizing RF- and microwave applications. RF-MEMS devices have a broad range of applications in military and commercial wireless communication, navigation and sensor systems. Agile RF-systems require reconfigurable frontends that can steer the beam over a wide frequency range.

Investigating the Performance of RF MEMS Switches

2006 IEEE International Conference on Semiconductor Electronics, 2006
The performance of micro-electro-mechanical system (MEMS) metal switches were investigated at wide temperature range. Measurements were carried out using cryogenic probe station and S-parameters were taken using a network analyser for frequencies up to 20 GHz. A total of 28 switches were evaluated.

Scalability of Capacitive RF MEMS Switches

2001
MEMS capacitive shunt switches have attracted large interest in various microwave or mm-wave applications, such as low power communication systems or phased arrayed antennas [1,2,3]. Two types of RF MEMS switches are discussed with respect to their impedance matching, scalability in frequency and related mechanical limitations.

Performance and Dynamics of a RF MEMS Switch

2001
A torsional RF-switch with low actuation voltage for use in mobile communication is presented. The device is fabricated in a BiCMOS compatible process with an additional back-end electroplating procedure. Electrical characterization from DC up to 6 GHz has been performed showing good RF characteristics. Optical measurements of the first resonance modes

Charge trap investigation methodology on RF-MEMS switches

2011
We hereby discuss effects and consequences of using certain measurements approaches on the charge trap analysis of RF-MEMS switches during cycling tests. We analyze how measurements are affected when the shape of the pulse changes, when the cycling frequency decrease and when measurements are carried out as a function of temperature.
