  • Patent number: 5274627
    Abstract: An apparatus and method for a non regenerative multibeam communications system with FDMA access and SSTDM connectivity. In accordance with the present invention, FDM input signals are transformed into corresponding TDM input signals. The TDM input signals are matrix switched and routed along the desired output transmission path(s). The TDM input signals routed along each output transmission path are then transformed into corresponding FDM output signals prior to further processing or transmission. The apparatus and method make it possible to provide full interconnectivity using time domain processing in a FDMA/FDM system.

  • Patent number: 4006434
    Abstract: There are provided for radar applications microwave multigate junctions that utilize excitation of peripheral modes. The conductor structure is applied to a ferrite, that is magnetized perpendicularly to the plane of its mass. The arrangement presents, through adaptation between the TEM mode and the peripheral mode, an effective distribution of the permeability of the ferrite which is spatially non-uniform in correspondence with tapering zones of the conductor which serves for the coupling of transmission lines.
