This paper presents a chip-level integration of radio-frequency (RF) microelectromechanical systems (MEMS) air-suspended circular spiral on-chip inductors onto MOSIS RF circuit chips of LNA and VCO using a multi-layer UV-LIGA technique including SU-8 UV lithography and copper electroplating. A high frequency simulation package, HFSS, was used to determine the layout of MEMS on-chip inductors wi...

This paper presents the design and realization of a low power, high speed circuit used to actuate RF MEMS (Radio Frequency MicroElectroMechanical Systems) based phase shifters at 60GHz.The phase shifter are used to realize beam forming reconfigurable antenna for high data rate WPAN (Wireless Personal Area Network) applications. RF MEMS commonly have high actuation voltages usually obtained with...

In the current communications market, there exists a great demand for devices, which function as passive signal processing units. High performance and small size are identified to be the bottlenecks to meet market demand in communications area[1,3]. MEMS or micromachining technology can yield small, low weight and high performance components to replace the currently used off-chip components. Th...

Introduction: Microwave filters are critical components for electronic warfare, radar, and communications systems, but typical tunable filters are bulky, expensive, and consume large amounts of power. Radio frequency microelectromechanical systems (RF MEMS) technology provides the possibility of low-loss, high linearity filtering in volumes comparable to those of integrated circuits [1]. The ma...

Micromechanical (or “μmechanical) communication circuits fabricated via IC-compatible MEMS technologies and capable of low-loss filtering, mixing, switching, and frequency generation, are described with the intent to miniaturize wireless transceivers. Possible MEMS-based receiver front-end architectures are then presented that use these micromechanical circuits in large quantities to enhance ro...

Recent advances in the Micro Electro-Mechanical System (MEMS) technology have made wireless MEMS accelerometers an attractive tool for Structural Health Monitoring (SHM) of civil engineering structures. To date, sensors' low sensitivity and accuracy--especially at very low frequencies--have imposed serious limitations for their application in monitoring large-sized structures. Conventionally, t...

The expending development of wireless communication requires strong demands for components with improved capabilities. RF MEMS devices offer a variable alternative to conventional communication components because they consume less DC power, have lower losses, higher linearity and higher Q factor. However, the commercialization of RF MEMS devices is hindered by technological issues such as their...

This paper presents a new monolithic microwave integrated circuit (MMIC) based on coplanar waveguide (CPW) design for a tunable resonator based on RF MEMS. This RF structure, which can be used for system on chip (SOC), is constituted with MEMS Bridge placed between two meander inductors and the tenability is controlled by a variable applied DC voltage. Moreover, this device presents a compactne...
