Latest Patents

One of Guan-Guo Cheng's key patents is for a phase shifter and electronic switch. This invention relies on a reflected wave from a load, such as a varactor, with a capacitance that can be varied by an external bias voltage. The unique aspect of this phase shifter is that the phase shift does not depend on wave propagation through an active medium. The input RF signal is directed to the variable loading, and the reflected wave is channeled to the output port through a network that minimizes reflection back to the input terminal. This network allows for the efficient transfer of power from the variable load to the output terminal, with a phase change that corresponds to the variable bias input of the loading. The network may include components such as a quadrature hybrid or a circulator to achieve this functionality.
