Title: Innovations by Francis Chan Wai Po
Introduction
Francis Chan Wai Po is a notable inventor based in Grenoble, France. He has made significant contributions to the field of radiofrequency technology, particularly in antenna impedance matching. With a total of 2 patents, his work has advanced the efficiency and effectiveness of communication systems.
Latest Patents
Francis Chan Wai Po's latest patents include an "Impedance matching method for a multiband antenna" and a "transmission or receiver channel having automatic matching." The first patent describes an automatic antenna impedance matching method for a radiofrequency transmission circuit. This method involves inserting an impedance matching network between an amplifier and an antenna. The output current and voltage of the amplifier, along with their phase difference, are measured using a variable measurement impedance. The complex load impedance of the amplifier is then deduced, allowing for the calculation of the antenna impedance based on this complex impedance and the known current values of the matching network. New values for the matching network are calculated to ensure the load matches the nominal impedance of the amplifier.
The second patent focuses on a method for automatically matching the antenna impedance for a radiofrequency transmission circuit with an amplifier. Similar to the first patent, an impedance matching network is inserted between the amplifier and the antenna. The output current and voltage from the amplifier are measured, and the complex impedance is deduced from these values. The antenna impedance is calculated based on this complex impedance and the known values of the adjustable impedances of the matching network. New values for the adjustable impedances are then calculated to achieve an overall load impedance that closely matches the nominal load impedance of the amplifier.
