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.

Distributed high efficiency RF supply

A compact design for the electronic circuits to provide electrical contact to a SED roll of a segmented electrode development unit is provided. In this invention, all the required high voltage and low voltage circuitry is placed on a printed flexible circuit which is folded and rolled into a cylindrical circuit to be connected to the SED roll. The flexible printed circuit has a plurality of output terminals each of which will be connected to one of the electrodes of the SED roll.

There is disclosed a compact design for the electronic circuits required to provide electrical contact to a SED roll of a segmented electrode development unit. In this invention, all the required high voltage and low voltage circuitry is placed on a printed flexible circuit which is folded and rolled into a cylindrical circuit to be connected to the SED roll. The flexible printed circuit has a plurality of output terminals each of which will be connected to one of the electrodes of the SED roll. In this invention, a spool is used to support the connection of the cylindrical circuit to the SED roll.

A low profile interconnect is used for electronic connections to segmented electrode donor rolls in which at least 78 interconnections between the segmented donor roll and a commutator can be made with a profile of approximately 10-15 mils, which retains reliability in an approximately 600 rpm rotational environment and which withstands 2000 volts between adjacent lines.
