Title: Fred Tanjutco: Innovator in Digital Beamforming Technology
Introduction
Fred Tanjutco is a notable inventor based in Cherry Hill, NJ (US). He has made significant contributions to the field of digital beamforming technology, holding a total of 3 patents. His work primarily focuses on enhancing the capabilities of phased array antennas, which are crucial in various applications, including radar and communication systems.
Latest Patents
One of Tanjutco's latest patents is for a digital beamforming phased array. This invention features a transmitter that includes an array antenna and multiple transmitter modules. Each module is equipped with a phase-lock loop that utilizes a slipped-cycle counter to determine the number of cycles of slippage before locking. A source of frequency reference signals is connected to each module's phase-lock loop through a path of unknown length. The phase of the reference signals is adjusted based on the number of slipped cycles, and a phase or delay corrector compensates for differences among the modules. The modules amplify the signals for transmission and apply these amplified signals to the antenna array via controlled-length paths.
Another significant patent is for a nearfield testing architecture. This open architecture design allows for a digital nearfield test system that efficiently tests a phased array antenna. It enables the components of an individual phased array antenna to be tested alongside a nearfield scanner probe system, creating a cost-effective "radar testing the radar" scenario.
