Latest Patents

Mark M Doherty holds a patent for an invention titled "Array Built-In Test." This patent describes built-in test circuitry for an array transmitter. The circuitry includes a directional coupler with directivity equal to the mutual coupling between adjacent antenna elements. The direct input port of the coupler is connected to the antenna element, while the direct output port is connected to the circuitry generating the signal transmitted by the antenna element. The coupled port of the coupler feeds a detector, which in turn provides an input to a control circuit. This circuit can be controlled to test, for each antenna element, the RF power driving each antenna element, the effective power radiated from each element, and the operation of the phase shifter coupled to each antenna element.
