  • Broadband matching circuit for capacitive device
    Patent number: 10218332
    Abstract: A matching circuit provides broadband impedance matching of first and second devices for processing RF signals in a broadband frequency range, the first device being inherently capacitive. The matching circuit includes a shunt inductor that transforms impedance of the first device to matching impedance at a matching resonance frequency in a middle portion of the broadband frequency range, and a series resonance circuit that has a series resonance frequency approximately the same as the matching resonance frequency. The series resonance circuit includes an inductor and a capacitor connected in series to the first device, and further transforms the matching impedance of the first device and the shunt inductor to a design matching impedance corresponding to the broadband frequency range. One end of the shunt inductor is connected to the first device, between the series resonance circuit and the first device or to an opposite side of the first device.
