Description
5 Watt RF Drivers for Acousto-Optic Modulators
The A35xxx RF driver provides up to 5 Watt output power. Various types cover a frequency range from 40 to 350 MHz. The maximum RF output power is adjustable by an internal potentiometer. The analogue modulation voltage controls the output power from 0 to 100% of the adjusted maximum power.
Additionally to the analogue modulation voltage a digital modulation control signal can switch on and off the RF power. An operation scheme below (page 5) illustrates the interaction of the two modulation signals in detail.
Both the analogue and digital modulation are characterized by extraordinary on/off ratios of at least 65dB.
The driver can be operated with modulation frequencies (analogue and digital) up to 25% of the carrier frequency and 50 MHz maximum.
Optimum EMC shielding and mechanical protection is achieved by an aluminium casing. The base plate serves for mounting as well as for heat dissipation.
Key Features:
- Frequency range 40 to 350 MHz
- RF output power 5 Watt
- RF on/off ratio > 65 dB
- Constant output power design
- Models with a modulation frequency up to 50 MHz available
- Conductive cooling through base plate
- Compact casing, fully shielded (EMC)
Applications:
- Fast modulation components for extra cavity applications, e. g. laser projection systems
- Frequency shifting
