Abstract
An acoustic inkjet print head having the RF generator and amplifier located at the load location for directly driving the load is disclosed. In so doing the power distribution medium, e.g. transmission line and any power divider device are eliminated. The overall power efficiency can be near to the high efficiency amplifier. In the case of Class-E, greater than 90 percent efficiency can be achieved. Due to the miniaturization of components the high efficiency power supply can be shielded effectively to minimize EME and can be further be integrated to a MCM or IC.
