Abstract

Utilizing Litz wire characteristics in the construction of Megasonic components achieves lower temperatures, higher operating efficiencies, and the ability to deliver more power at higher frequencies with less cooling.

Claims

1. In an amplifier used to generate a RF signal for the purpose of driving a piezo electric transducer at or above 500 kHz.

2. In the construction of magnetics used in the amplifier and impedance matching networks.

3. In the construction of the power transformer(s) in the amplifier to generate a frequency of 500 kHz or higher.

4. In the construction of an impedance matching network to be used either inside the amplifier or between the output of the amplifier and the transducer.

5. In the fabrication of cabling, connecting the amplifier to the piezo electric transducer.
