The switched varactor for high power RF signals is described in this article. This varactor can perform tuneable capacitor operations up to 10 GHz frequencies. The RF micro-electro-mechanical systems (MEMS) has become an atractive area of research in the recent. Devices like tuners, antenna beam forming networks and reconfigurable filters all will benefit from this.

Abstract
MEMS varactors are one of the important passive MEMS devices. Their applica- tions include use in VCOs, tunable impedance matching networks, tunable ¯lters, phase shifters, and true time delay lines. The shunt capacitive structure has been employed in most of the conventional MEMS varactor designs because of its simplicity. However, the capacitance ratio of this conventional shunt capacitive MEMS varactor is limited to 1.5 because of the MEMS Pull- In e®ect, which happens when the de°ection between the MEMS top and bottom m ....etc

Micro-electro Mechanical Systems (MEMS)

Introduction
The satellite industry could experience its biggest revolution since it joined the ranks of commerce, thanks to some of the smallest machines in existence. Researchers are performing experiments designed to convince the aerospace industry that microelectromechanical systems (MEMS) could open the door to low-cost, high-reliability, mass-produced satellites.MEMS combine conventional semiconductor electronics with beams, gears, levers, switches, accelerometers, diaphragms, microfluidic thrus ....etc

A Paper Presentation on Software Development Automation by Computer Aided Software Engineering (CASE)



Abstract: Nowadays, system developers are faced to produce complex, high quality software to support the demand for new and revised computer applications. This challenge is complicated by strict resource constraints, forcing management to deploy new technologies, methods and procedures to manage this increasingly complex environment. Often the methods, procedures and technologies ar ....etc

MicroElectroMechanical Systems, MEMS, are systems based on a range of techologies whereby tiny mechanical elements, both sensors and actuators, can be implemented.It turns out that these elements have excellent system properties.The elements are often interfaced to microelectronical driving or sensing components (ICs) by appropriate packaging or on the same silicon wafer. The semiconductor silicon is not only good for making electronics but its material properties are extremely good.Thus, Micro electromechanical systems (MEMS) refer to a collec ....etc
