Linearity and RF Power Handling of Capacitive RF MEMS Switches
2019 IEEE MTT-S International Microwave Symposium (IMS), 2019Linearity characteristics of capacitive tuners under large radio frequency (RF) power have become an important issue for today’s cellphone industry. The use of these devices as antenna tuners has become critically important due to the RF spectrum opening in the low-frequency range.

RF MEMS Switch with Enhanced Reliability
2018 IEEE International Symposium on Radio-Frequency Integration Technology (RFIT), 2018In this paper, a novel RF MEMS shunt switch with enhanced reliability is presented. A Ka-band shunt switch which is fabricated on a high resistivity silicon substrate implements a novel concept of tri-layer sandwich (insulator-Metal-insulator) membrane which results a lower actuation voltage of 10 Volt.

Miniature RF MEMS switch matrices
2009 IEEE MTT-S International Microwave Symposium Digest, 2009A novel miniature-size switching unit is reported for application as the building block of multiport switch matrices. The cell consists of 3 cantilever-beam contact type MEMS devices coupled to CPW transmission lines. A major feature of the proposed switch cell is that in each of the operating states there is only one MEMS switch located in the path of

Miniature MEMS Switches for RF Applications
Journal of Microelectromechanical Systems, 2011This paper presents a new way to design MEMS (microelectromechanical system) metal contact switches for RF applications using miniature MEMS cantilevers. A single 25 × 25 μm switch is first demonstrated with a Au-to-Ru contact, Cu = 5 fF and Ron = 7 Ω at an actuation voltage of 55 V. The measured switching time is 2.2 μs and the release time is

Development and optimization of RF MEMS switch
Microsystem Technologies, 2019Isolation and actuation voltages are important parameters in micro-electro-mechanical switches. These parameters can be destroyed by the effect of creating bulge and erosion in the surface of the beam. In this paper, a fabrication method is proposed to create a smooth and flat beam.
