  • Patent number: 8570237
    Abstract: A multi-band electronically scanned array antenna including a first sub-assembly having electronic circuits for a first frequency band; a second sub-assembly mechanically coupled to the first sub-assembly and having electronic circuits for a second frequency band; and an aperture adjacent to the first sub-assembly, the aperture being shared by the first sub-assembly and the second sub-assembly. The array antenna may further include a band switching circuit, or a combining circuit for coupling the first sub-assembly or the second sub-assembly to the aperture. The array antenna may also include a third sub-assembly including electronic circuits for a third frequency band. In this way, the aperture is shared by the first sub-assembly, the second sub-assembly, and the third sub-assembly to provide a smaller and lighter array antenna.

  • Patent number: 8427238
    Abstract: Aspects of embodiments according to the present invention are directed toward a circuitry and a method to accurately measure the junction temperature of power amplifier and uses the measurement to enable optimization of performance in the presence of a mismatched load via control of the power amplifier such that corrective action to mitigate effects of the mismatched load can be performed.

  • Patent number: 8405548
    Abstract: According to one embodiment, an antenna apparatus includes first and second antenna arrays configured in a support structure. Each antenna array has multiple antenna elements that transmit and/or receive electro-magnetic radiation. The elements of the first antenna array are oriented in a boresight direction that is different from the boresight direction in which the elements of the second antenna array are oriented. A plurality of switches alternatively couples the first antenna elements or the second antenna elements to a signal distribution circuit.
