Latest Patents

James Henry Campbell holds a patent for an "Electrostatically actuated non-latching and latching RF-MEMS switch." This RF MEMS switch apparatus features a planar substrate and an electrostatic actuator formed thereon. The actuator consists of two sets of interdigitated combs that facilitate the movement of an armature and a shunt contact head. The armature connects to the substrate through a main return spring and one or more contact head support springs. The shunt contact head includes a primary shunt contact and one or more spring-loaded sacrificial contacts. In its relaxed position, the switch is off, but when actuated, the primary shunt contact makes direct mechanical contact with both the stationary input and output electrodes. The switch remains closed as long as the actuator is powered, and the springs return the armature to its relaxed position when power is removed. This invention showcases Campbell's expertise in creating advanced RF switch technology.
