Studies on RF MEMS shunt switch
Radio Frequency Micro-Electro-Mechanical-Systems (RF MEMS) based switches are expected to play a key role in the field of microwave switching. Traits like low-loss performance; zero-power consumption and very low inter-modulation distortion have made these switches well suitable for high-performance microwave and millimeter-wave circuits. The design of RF MEMS switches, however, require sophist...
متن کاملDesign 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...
متن کاملA High Isolation Series-Shunt RF MEMS Switch
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...
