Abstract: Power combiners and associated methods of manufacturing are provided. An example power combiner includes a plurality of power input structures each of which defines a waveguide that receives a respective electromagnetic radiation input from a respective power source and a central combining conduit. The central combining conduit receives the respective electromagnetic radiation inputs communicated via respective power input structures and combines the respective electromagnetic radiation inputs into a combined power signal for output via an output port communicably coupled with the central combining conduit. The central combining conduit defines a waveguide structure that is configured to minimize insertion loss between the respective electromagnetic radiation inputs and the combined power signal.

Abstract: Systems, apparatuses, semiconductor products and methods for semiconductor packages, specifically under chip bridge system-in-packages, are provided that allow one or more bridges to connect two or more dies. For example, high density connections of two or more dies may be connected with an under chip bridge, all of which may be placed on a substrate to form a system-in-package semiconductor package. Various embodiments include methods of manufacturing such packages that include utilizing a flat semiconductor along with bumping operations that may use single sizes of bumping.

Abstract: Apparatuses, systems, and methods for dual processor single board computers are provided. For example, a dual processor single board computer may include a management processor with associated memory, an application co-processor with associated memory, and a plurality of bus switches. The dual processor single board computer may be used in devices that may be exposed to radiation, such as satellites. During a radiation event, the management processor may continue operation and isolate the application co-processor and certain memories to cease operation to increase the amount of radiation safely received before damage. After the radiation event, the management processor may reboot the application co-processor, and update applications to allow a device to continue its mission.

An example power combiner includes a plurality of power input structures each of which defines a waveguide that receives a respective electromagnetic radiation input from a respective power source and a central combining conduit. The central combining conduit receives the respective electromagnetic radiation inputs communicated via respective power input structures and combines the respective electromagnetic radiation inputs into a combined power signal for output via an output port communicably coupled with the central combining conduit.

Abstract: Systems, apparatuses, and methods that compensate for total ionizing doses and intrinsic base currents in transistors of a bandgap reference circuit are provided. A compensation circuit can include a compensation transistor with a size and one or more bias conditions that are based at least in part on a respective bipolar transistor of a bandgap reference circuit. The compensation circuit can include an operational amplifier that is configured to: (i) set a base-collector voltage of the compensation transistor to zero; and (ii) provide a compensation base current to a base terminal of the compensation transistor that is representative of at least a radiation-induced current transistor or an intrinsic base current for the respective bipolar transistor. A bandgap reference circuit can be augmented with one or more compensation circuits to accommodate for a total ionizing dose and/or an intrinsic base current for one or more transistors of the bandgap reference circuit.

Abstract: Embodiments of a wide band multi-polarization antenna system are described, which can be attached to the back or front of a soldier's vest or backpack. The antenna system can allow for release of pre-shaped integral radiating elements that spring into a geometric configuration suitable for circular polarization radiation or linear polarization over a desired band of frequencies. The antenna system can provide, when collapsed, linear polarized line-of sight capability over a wide band of frequencies. In a collapsed low-profile state, the antenna system can remain on the soldier, but out of the way for maneuvering.
