Ge AOM RF Driver

125 Watt Germanium Acousto-optic Modulator driver

The HP041-125ADG-A10 RF driverprovides up to 125 Watt output power
at 40.68 MHz signal frequency. The
driver can be operated with modulation
frequencies (analogue and digital) up
to 1 MHz. An operation scheme (page 3)
illustrates the interaction of the twomodulation signals in detail.
Water cooling parts made from copper ensures highest
standards for corrosion protection.
Optimum EMC shielding and mechanical protectionis achieved by an aluminium casing and a conductive
surface passivation.
This product conforms to the requirements of theEuropean Union Directive 2011/65/EU of the EuropeanParliament and of the Council on the Restriction of theUse of Certain Hazardous Substances in Electrical andElectronic Equipment.

Key Features• RF output power up to 125 Watt
• Copper water-cooling path
• Constant output power design• High SWR and overheat safety shutdown• Compact casing, fully shielded (EMC)

Applications:• Industrial (material processing):·	PCB via drilling·	Marking and engraving·	Light guide panel processing·	Micro-perforation
