  • Patent number: 10439284
    Abstract: A phased-array antenna panel has front end modules mounted on a Printed Circuit Board (PCB). Several phased-array processing die, transform phase and gain according to a register array in an RFIC on the PCB. The register array are grouped into a local register group and a global register group. Each set of local registers control an individual antenna element and a global register group controls overall RFIC function. The apparatus elaborates phase shift weights into a submodule of a phased-array antenna system. Each submodule determines its own base phase shift weight per its unique location and configuration to accelerate antenna beam direction changes.

  • Patent number: 10270507
    Abstract: A system substantially updates all the phase shifter values of a phased array antenna by using two “global writes” to update these parameters to all phased-array transformation circuits simultaneously via a serial bus. Antenna elements, each controlled by a phased-array transformation circuit, are individually configured to transform phase and gain according to a register array. The register array has a local register group and a central register group, the local registers physically placed close in proximity to RF chains which each correspond to an element of array antenna, whereby each set of local registers control an individual antenna element and a central register controlling overall beam steering function. Gain values are hierarchically distributed. The apparatus is configured to efficiently elaborate phase shift weights into a submodule of a phase array antenna system with low noise and bandwidth.

  • Patent number: 10027028
    Abstract: A method of operation for a hierarchically elaborated phased-array antenna. Within a plurality of front end modules a phased-array processing die individually transforms phase and gain according to a register array. The register array in each RFIC is grouped into a local register group and a global register group, the local registers physically placed close in proximity to RF chains which each correspond to an element of array antenna, whereby each set of local registers control an individual antenna element and a global register controlling overall RFIC function. The method efficiently elaborates phase shift weights into a submodule of a phase array antenna system. Within each subarray phase control submodule the method recursively elaborates weights to control phase shifters. The method receives and transforms pairs of major operators and minor operators. The method distributes to each submodule determining its own base phase shift weight per its unique configuration.
