Abstract: Modern modulator drivers must be capable of delivering a large output voltage into a tens of ohms modulator, while minimizing the amount of distortion added by the driver. The driver should deliver the output voltage without exceeding a maximum distortion while minimizing the DC power consumption. Accordingly, a modulator driver includes a final stage amplifier with auxiliary transistors that turn on when the conventional differential pair of transistors approaches their maximum voltage of the linear region of their transfer function, thereby providing a more linear transfer function, in particular at large input voltages.

Abstract: The invention is directed to a process for producing metallic composite material in which there is applied to at least one side of a parent strand a material having different material characteristics. For this purpose, according to the invention, the parent strand is guided through a melt having the same material composition as the parent strand, wherein melt crystallizes on by inversion casting and, at a predefinable distance from the surface of the molten bath, a composite section is fed to the carrier section after it has exited from the molten bath, this composite section being welded with the surface of the carrier section. The invention is further directed to a device for carrying out the process.
