in this paper, a robust pid control scheme is proposed for micro-electro-mechanical-systems(mems) optical switches. the proposed approach is designed in a way which solves twochallenging and important problems. the first one is successful reference tracking and the second ismitigating the system nonlinearities. the overall system composed of nonlinear mems dynamicsand the pid controller is prov...

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...

Commercial Applications Solid state and electromagnetic relay switches are being replaced by MEMS switches due to their lower costs and increased application performance. Some of the benefits of MEMS switches include low power consumption, long life cycle, linearity and increased switching speeds. Applications include highspeed digital channel switching in automated test equipment, filter bank ...

The paper explores the modelling and simulation of a Radio Frequency Micro Electro-Mechanical Systems (RF MEMS) switch with the use of a novel seesaw design providing Double-Pole Double-Throw (DPDT) functionality. This optimises the capabilities of the seesaw design structure for use in mobile communications systems and devices. After researching other available seesaw designs, it was realised ...

This paper presents a wide band compact high isolation microelectromechanical systems (MEMS) switch implemented on a coplanar waveguide (CPW) with three ohmic switch cells, which is based on the series-shunt switch design. The ohmic switch shows a low intrinsic loss of 0.1 dB and an isolation of 24.8 dB at 6 GHz. The measured average pull-in voltage is 28 V and switching time is 47 μs. In order...

We propose and demonstrate a wavelengthand time-selective reconfigurable optical add/drop multiplexer (ROADM) using timefrequency domain processing. The proposed ROADM is realized by allocating wavelength channels and time slots to corresponding 2D spatial channels on a MEMS optical switch. Experimental results show the wavelengthand time-selective drop operation for a signal with equivalent 3....

− A new type of RF MEMS switch for low voltage actuation, high broadband application and high power capability is presented. Mechanical and electromagnetic simulations of this new RF MEMS switch type are shown and the fabrication process and measurement results are given. The switching element consists of a cantilever which is fixed by a suspension spring to the ground of the coplanar line. The...

This paper mainly studied the leads reliability of the novel solid MEMS switch under high impact and the influence of some factors such as the current and thermal on the leads by FEM simulation analysis. Through simulation analysis, the mainly weakness and the potential failure modes of the leads under high impact can be obtained, which can provide theory reference for the design and applicatio...
