Abstract
An electrical arrangement for performing radio frequency isolation for microelectromechanical relay switches. A microelectromechanical relay switch comprises a beam configured to switch from a first position connected to an upper voltage source to a second position connected to a lower voltage source. The microelectromechanical relay switch further comprises at least one frequency isolation circuit or resistor disposed adjacent to the beam. The at least one frequency isolation circuit or resistor biases a direct current potential to allow for electrostatic actuation and further provides a path for transient electrical currents during switching.
Claims22
An electrical arrangement, comprising:
- a first microelectromechanical relay, the first microelectromechanical relay comprising a beam element configured to switch from a first position adjacent to a first electrode to a second position adjacent a second electrode;
- a first RF electrode and second RF electrode configured to be either electrically isolated or electrically coupled to the beam element in the following manner depending on the beam element position:
- when the beam element is in the first position adjacent to the first electrode, the first and second RF electrodes are coupled to the beam element;
- when the beam element is in the second position adjacent to the second electrode, the first and second RF electrodes are electrically isolated.
