125W Germanium Acousto-Optic Modulator RF Driver HP041-125ADG-A10
HP041-125ADG-A10 is a high-power RF driver specifically designed for germanium acousto-optic modulators. It operates at 40.68 MHz, providing up to 125 W RF output into a 50 Ω load and supporting both analog and digital modulation. Copper water-cooling channels provide excellent heat dissipation and long-term corrosion resistance. Its aluminum-alloy enclosure with conductive surface passivation provides mechanical protection and excellent electromagnetic compatibility (EMC) shielding. It is particularly suitable for high-power AOM systems, laser processing equipment, scientific research platforms, and industrial beam control. Note: the stated performance specifications were measured with a 50 Ω load.
