Radio Frequency-micro Electromechanical System Switch with High Speed and Low Actuated Voltage

Ultra High-Speed Radio Frequency Switch Based on Photonics

Microwave switches, or Radio Frequency (RF) switches have been intensively used in microwave systems for signal routing. Compared with the fast development of microwave and wireless systems, RF switches have been underdeveloped particularly in terms of switching speed and operating bandwidth. In this paper, we propose a photonics based RF switch that is capable of switching at tens of picosecon...

Design and simulation of a RF MEMS shunt capacitive switch with low actuation voltage, low loss and high isolation

According to contact type, RF MEMS switches are generally classified into two categories: Capacitive switches and Metal-to-Metal ones. The capacitive switches are capable to tolerate a higher frequency range and more power than M-to-M switches. This paper presents a cantilever shunt capacitive RF MEMS switch with characteristics such as low trigger voltage, high capacitive ratio, short switchin...

Low-voltage shock-mitigated micro-electromechanical systems structure

High-speed transparent switch via frequency upconversion.

We demonstrate a novel all-optical switch based on frequency upconversion. The switch features advantages for telecommunications: it is fast, transparent, frequency-multiplexable and bias-free.

Robust Fractional Order Control of Under-actuated Electromechanical System

This paper presents a robust fractional order controller for flexible-joint electrically driven robots under imperfect transformation of control space. The proposed approach is free from manipulator dynamics, thus free from problems associated with torque control strategy in the design and implementation. As a result, the proposed controller is simple, fast response and superior to the torque c...
