  • Matching circuit for megasonic transducer device
    Publication number: 20040007945
    Abstract: A method and apparatus for matching impedance magnitude and impedance phase for an acoustic- wave transducer load and an RF power source. The acoustic-wave transducer load has a load impedance magnitude and phase. The RF power source has a source impedance magnitude and phase. In one embodiment of the invention, a transformer matches the source and load impedance magnitudes. A capacitor, connected in series with the transformer, matches the source impedance phase to the load impedance phase.
