Latest Patents

Chang holds a patent for a "Switchable N-way power divider/combiner." This invention is an improved Wilkinson-type power divider/combiner that possesses switching capabilities for selectively controlling the operative modes of its constituent dividing and combining channels. The switchable power divider/combiner includes N first switches that connect N input/output transmission lines to a common junction, along with N second switches that connect N isolation resistors to a common node. The operating mode can be controlled by activating each pair of the first and second switches to either a closed or open position. The impedance values of the dividing and combining channel transmission lines are adjusted to provide optimal impedance matching in both N-way and (N-1)-way operating modes. This innovation allows for efficient power combining and distribution in a low-loss, phase-balanced manner. In the event of a failure in one of the signal-processing channels, the system can switch to the (N-1)-way mode, ensuring continued operation without degradation in signal characteristics.
