G&H RF Driver

Operating frequency range: 40-300 MHz
Rise time as low as 4 ns
Modulation method: digital or analog

The main function of the radio frequency (RF) driver for an acousto-optic modulator is to generate RF signals with specific frequencies, power levels, and waveforms to modulate the light beam. LBTEK offers RF drivers with various frequencies that can be paired with different acousto-optic modulators. Three modulation modes are provided: digital, analog, and analog+digital. The modulation mode determines how the applied RF power varies, thereby controlling the intensity of the diffracted light. In digital modulation, the RF power is turned on/off via TTL signals, controlling whether the beam is diffracted. In analog modulation, the RF power is controlled by applying a voltage within a specified range, enabling precise control of diffraction efficiency and waveform shaping. For custom RF output power and modulation mode requirements, LBTEK provides tailored solutions. Please consult our technical support for detailed information.
