Ge AOM RF Driver
125 Watt Germanium Acousto-optic Modulator driver
The HP041-125ADG-A10 RF driver provides 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 illustrates the interaction of the two modulation signals in detail.
Water cooling parts made from copper ensures highest standards for corrosion protection.
Optimum EMC shielding and mechanical protection is achieved by an aluminium casing and a conductive surface passivation.
This product conforms to the requirements of the European Union Directive 2011/65/EU of the European Parliament and of the Council on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment.
