WiSpry, Inc. is a fabless RF semiconductor company based in Irvine, California.Using RF MEMS technology, WiSpry develops and markets RF Silicon integrated circuits, components and modules to manufacturers of wireless communication products.Founded in 2002, WiSpry was initially funded by the angel investor network, Tech Coast Angels.WiSpry is now one of Orange County's more highly funded startups with almost $50M invested to date by Acadia Woods Partners, American River Ventures, Arkian, Blueprint Ventures, Chart Venture Partners, DoCoMo Capital, Hotung Capital Management, Inc., In-Q-Tel,L Capital Partners, MuRata Manufacturing Co., Ltd., Paladin Capital Group, Shepherd Ventures and Tech Coast Angels.In January 2012, a Samsung smartphone teardown revealed the existence of a WiSpry RF MEMs antenna tuning chip: this is believed to be the first known use of an RF MEMs device in a volume shipping product.

Patent
WiSpry | Date: 2015-10-13

The present subject matter relates to systems and methods for sealing one or more MEMS devices within an encapsulated cavity. A first material layer can be positioned on a substrate, the first material layer comprising a first cavity and a second cavity that each have one or more openings out of the first material layer. At least the first cavity can be exposed to a first atmosphere and sealed while it is exposed to the first atmosphere while not sealing the second cavity. The second cavity can then be exposed to a second atmosphere that is different than the first atmosphere, and the second cavity can be sealed while it is exposed to the second atmosphere.


The present subject matter relates to devices, systems, and methods for isolation of electrostatic actuators in MEMS devices to reduce or minimize dielectric charging. A tunable component can include a fixed actuator electrode positioned on a substrate, a movable actuator electrode carried on a movable component that is suspended over the substrate, one or more isolation bumps positioned between the fixed actuator electrode and the movable actuator electrode, and a fixed isolation landing that is isolated within a portion of the fixed actuator electrode that is at, near, and/or substantially aligned with each of the one or more isolation bumps. In this arrangement, the movable actuator electrode can be selectively movable toward the fixed actuator electrode, but the one or more isolation bumps can prevent contact between the fixed and movable actuator electrodes, and the fixed isolation landing can inhibit the development of an electric field in the isolation bump.

The present subject matter relates to systems, devices, and methods for adaptively tuning antenna elements and/or associated filter elements to support multiple frequency bands. For example, a tunable filter having an input node and an output node can be selectively tunable to define one or more pass bands associated with one or more first signal bands and one or more reject bands associated with one or more second signal bands. The tunable filter can be configured to pass signals having frequencies within the first signal bands between the input node and the output node and to block signals having frequencies within the second signal bands. Furthermore, the tunable filter can be configured to selectively tune the pass bands to have a minimum pass band insertion loss at any of a variety of frequencies, including frequencies that are greater than and less than frequencies within the reject bands.

The present subject matter relates to tunable antenna systems and methods in which a tunable band-stop circuit is provided in communication between a signal node and an electrically small antenna having a largest dimension that is substantially equal to or less than one-tenth of a length of a wavelength corresponding to a frequency within a communications operating frequency band. The tunable band-stop circuit can be tunable to adjust a band-stop frequency.


Devices and methods of operating partitioned actuator plates to obtain a desirable shape of a movable component of a micro-electro-mechanical system (MEMS) device. The subject matter described herein can in some embodiments include a micro-electro-mechanical system (MEMS) device including a plurality of actuation electrodes attached to a first surface, where each of the one or more actuation electrode being independently controllable, and a movable component spaced apart from the first surface and movable with respect to the first surface. Where the movable component further includes one or more movable actuation electrodes spaced apart from the plurality of fixed actuation electrodes.
