Title: The Innovations of Franco Marconi
Introduction
Franco Marconi is a notable inventor based in Monza, Italy. He has made significant contributions to the field of microwave technology, holding a total of 3 patents. His work focuses on advanced filtering techniques that enhance the performance of microwave circuits.
Latest Patents
One of his latest patents is a comb-line band-pass filter designed for the microwave field. This innovative filter features a circular cross-section and is composed of internal rods that act as resonators. These rods are brought to resonance using tuning screws and are arranged in a manner where each rod is rotated relative to the previous one by an angle between 0 degrees and 90 degrees. The placement of coupling screws at an intermediate angle allows for equal electrical characteristics, with the filter's length also being a function of the rotation angle of the rods.
Another significant patent by Marconi is a wideband microwave hybrid circuit that provides either in-phase or phase-inverted output. In this design, a half-wave line section is connected to one output terminal of the hybrid circuit, while a low attenuation filtering network is connected to the second output terminal. This filtering network has a phase characteristic of -90 degrees at the center frequency, which varies with frequency similar to a half-wave line section.
Career Highlights
Throughout his career, Franco Marconi has worked with prominent companies in the telecommunications sector. Notably, he has been associated with GTE Telecomunicazioni S.p.A. and Siemens Telecomunicazioni S.p.A. His expertise in microwave technology has made him a valuable asset in these organizations.
