  • Patent number: 10305199
    Abstract: In an exemplary embodiment, a phased array antenna comprises multiple subcircuits in communication with multiple radiating elements. The radio frequency signals are independently adjusted for both polarization control and beam steering. In a receive embodiment, multiple RF signals of various polarizations are received and combined into at least one receive beam output. In a transmit embodiment, at least one transmit beam input is divided and transmitted through multiple radiating elements, with the transmitted beams having various polarizations. In an exemplary embodiment, the phased array antenna provides multi-beam formation over multiple operating frequency bands. The wideband nature of the active components allows for operation over multiple frequency bands simultaneously.

  • Patent number: 9368854
    Abstract: In general, in accordance with an exemplary aspect of the present invention, an electrical system configured to use power combining of microwave signals, such as those from monolithic microwave integrated circuits or MMICs is provided. In one exemplary embodiment, the system of the present invention further comprises a low loss interface that the circuits are directly connected to. In another exemplary embodiment, the circuits are connected to a pin which is connected to the low loss interface. In yet another exemplary embodiment of the present invention, a multi-layer power amplifier is provided that comprises two or more chassis and circuits attached to impedance matching interfaces according to the present invention. This multi-layered power amplifier is configured to amplify an energy signal and have a significantly reduced volume compared to existing power combiners.

  • Patent number: 9035728
    Abstract: In an example embodiment, an electromagnetic interface can comprise: a first component comprising a first waveguide channel, a first interface surface, and a first force transfer feature; a second component comprising a second waveguide channel, a second interface surface, and a second force transfer feature; and a fastener that can be configured to force the first force transfer feature in sliding engagement with the second force transfer feature. The first and second force transfer features can be configured to interoperate to create an indirect force holding the first interface surface in contact with the second interface surface and holding the first waveguide channel in alignment with the second waveguide channel.

  • Patent number: 8957722
    Abstract: A double balanced image reject mixer (IRM) can be configured to comprise: a common radio frequency (RF) port; four mixer devices, each comprising an intermediate frequency (IF) port, an RF port and an local oscillator (LO) port; and a four-way, in-phase splitter/combiner. The four-way, in-phase splitter/combiner can be connected between the RF common port and the RF port of each of the four mixer devices. A method of performing spurious suppression and image reject mixing in a double balanced IRM, can comprise: directly in-phase combining radio frequency (RF) output signals of four mixer devices located in the double balanced IRM; and phase pairing local oscillator (LO) signals and intermediate frequency (IF) signals such that the combination of the phases of the respective IF and LO signals can result in substantially equal phase RF signals at the RF ports of all four mixer devices.
