N-type Acousto Optic Driver

Acousto-optic driver is an RF driver that provides supporting functions for acousto-optic device products. It is applicable to acousto-optic modulators and frequency shifter products with driving power less than 3W. The RF signal generated by the driver is used to generate ultrasonic waves in the crystal of the acousto-optic device. The frequency and intensity of the RF signal applied will determine the degree to which the beam is modulated, deflected, or tuned. The drive has good heat dissipation, and the use of a matched drive will bring better temperature stability.

Supporting DriveModel (SGXXXX-33-N-ab) “X” – use “Y” for frequency shift function, and “T” for modulation function; “XXX” – operating frequency “33” refers to RF output power; “N” indicates the package type; “A” – use “1” for power supply voltage 24V, “2” for power supply voltage 12V; “b” – use “D” for digital TTL modulation, and “A” for analog modulation.
