AOM Driver 2910 Series
1 to 4 Watt RF Drivers for Acousto-Optic Modulators
The 2910 Series RF driver provides up to 4 Watts output power. Various types cover a frequency range of 80 to 350 MHz.
The maximum RF output power is adjustable by an internal potentiometer. The driver is available in either analogue or
digital modulation control. The analogue modulation voltage controls the output power from 0 to 100% of the adjusted maximum power. The digital modulation control signal can switch on and off the RF power.
The driver can be operated with modulation frequencies (analogue and digital) up to 25% of the carrier frequency and 50 MHz maximum at the higher carrier frequencies.
Optimum EMC shielding and mechanical protection is achieved by an aluminium casing. The base plate serves for mounting and heat dissipation purposes.
Key Features:
- Frequency range 80 to 350 MHz
- RF output power up to 4 Watt
- RF on/off ratio ≥ 60 dB (Digital Modulation)
- RF on/off ratio ≥ 50 dB (Analogue Modulation)
- Constant output power design
- Models with a modulation frequency up to 50 MHz available
- Conductive cooling through base plate
- Compact casing
Applications:
- Fast modulation components for extra cavity applications, e. g. laser
projection systems
- Frequency shifting
