  • Four-post quadrature coupler suitable for monolithic implementation
    Patent number: 5128638
    Abstract: A method for creating a four-port quadrature coupler suitable for monolithic implementation which involves connecting two ports of a balun, suitable itself for implementation in monolithic microwave integrated circuits, to two separate phasing networks. A device exhibiting the proper four-port quadrature coupler characteristics within a MMIC structure results, with wide bandwidth exceeding one octave.

  • Field effect attenuator devices having controlled electrical lengths
    Patent number: 4998147
    Abstract: Overlapping gate electrodes are selectively energized to vary the electrical length and thus the resistance of the conductive path through a field effect attenuator. The electrical width can also be varied to provide additional control over the resistance.

  • Miniature wide-band microwave power divider
    Patent number: 4851795
    Abstract: A miniature wide-band microwave power divider comprising a common terminal connected to a plurality of parallel signal paths with each signal path comprising a low pass and a high pass filter made up of discrete components. Use of discrete components allows the entire power divider to be incorporated on a single chip. Isolation is achieved between the signal paths by isolation means comprising resistors.
