97-02910-xx product image - A G&H RF driver module in a rectangular metal housing with a front panel labeled with connection points and identifiers. The panel includes text such as “MODEL NO.”, “S/N SAMPLE”, “RF LEVEL ADJ.”, “AM IN”, and “RF OUTPUT”. There are visible coaxial connectors on the side and bottom for RF signal input and output. The unit is designed for driving acousto-optic modulators or Q-switches.

97-02910-xx

With an operating frequency of 80–350 MHz, a 4 W output into a 50-ohm load, and analog and digital modulation.
