Ultra low actuation voltage RF MEMS switch
In this brief a new low actuation voltage RF MEMS switch is presented which can be integrated and controlled with available CMOS technologies. Despite the advantages in the design of RF MEMS switches designing a low actuation voltage RF MEMS switch is still a challenging task. To overcome this problem, a small size RF MEMS switch utilizing a moving plate with multiple holes supported by a low s...
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 Parallel-plate-based Fishbone-Shape MEMS Tunable Capacitor with Linear Capacitance-Voltage Response
A novel fishbone-shape parallel-plate-based capacitor with high tunability and linear C-V response is presented. The electrodes consist of a set of lateral cantilever beams of different lengths, attached to a longitudinal fixed-fixed beam. An insulating layer prevents contact between the electrodes. When a DC voltage is applied, the longitudinal and lateral beams undergo out-of-plane deformatio...
متن کاملBi-stable RF MEMS switch with low actuation voltage
Mobile technologies have relied on RF switches for a long time. Though the basic function of the switch has remained the same, the way they have been made has changed in the recent past. In the past few years work has been done to use MEMS technologies in designing and fabricating an RF switch that would in many ways replace the electronic and mechanical switches that have been used for so long...
متن کاملDevelopment of a Low Actuation Voltage Rf Mems Switch
This paper reports on the design of a novel ultra low actuation voltage, low loss radio frequency micro-electro-mechanical system (RF MEMS) capacitive shunt switch. The concept of the switch relies on a mechanically unconstrained armature actuated over a coplanar waveguide using electrostatic forces. The minimum actuation voltage of the switch is <2V, with an isolation of 40dB and insertion los...
