Title: Innovations of Robert J Matreci
Introduction
Robert J Matreci is an accomplished inventor based in Santa Rosa, CA (US). He holds 2 patents that showcase his expertise in the field of vector signal modulation and millimeter wave technology. His innovative contributions have made significant impacts in various technological applications.
Latest Patents
One of Matreci's latest patents is a method for determining imbalance in a vector signal modulator. This method involves stimulating the first and second channels of a vector signal modulator with a multi-tone signal that has a power versus frequency spectrum containing numerous frequencies. The output of the modulator is measured in response to this stimulation. The channels are then simultaneously stimulated with a multi-tone signal that shares the same characteristics as the one used for separate stimulation. Data collected from both separate and simultaneous stimulations are utilized to calculate the imbalance versus frequency of the vector signal modulator. Additionally, he has developed a magnetically tuneable millimeter wave bandpass filter that combines four hexagonal ferrite spheres under a single electromagnet structure. This filter achieves high off-resonance isolation while maintaining reasonable insertion loss, making it suitable for applications such as preselectors for swept-frequency signal analyzers.
