Latest Patents

One of his latest patents is a method and apparatus for improving the accuracy of a phase shifter. This innovative phase shifter utilizes cascaded phase shifting modules that require only one pair of control voltage leads, significantly reducing electromagnetic interference. This advancement allows for the phase of an incoming pulse train to be shifted from 0 to 360 degrees in 3-degree increments with ±1-degree accuracy. This technology is particularly beneficial in long-haul fiber-optic cable networks, enabling error-free transmission over distances of up to 2500 miles without the need for regeneration units.

Another significant patent is a microwave modulator featuring adjustable couplers. This multifunction microwave modulator circuit includes an input signal splitter that provides two equal amplitude signal components. By employing a Lange coupler, a phase quadrature relationship is achieved between the two signal components. Each circuit cell operates separately on one of the signal components, allowing for electronic adjustments to the vector representation of the signal. The output signal can be represented by a resultant vector with any direction within 360 degrees, showcasing the versatility of this technology.
