RF drivers for Deflectors & Agile Frequency Shifters

Additional information

VCO drivers (Voltage Controlled Oscillator)

These drivers are suitable for general purpose applications (raster scan, or random access...). The VCO can be modulated (amplitude) from an external signal.
The frequency is externally controlled by an analog signal. An external medium power amplifier will be required to generate the RF power levels required by the AO device.

DDS drivers (Direct Digital Synthesizer)

To get a high resolution driver with fast switching time, AA has designed direct digital synthesizers based on monolithic IC circuits. 3 models have already been released, and different units can be designed to specific requirements.
These models offer high frequency accuracy and stability and extremely fast switching times, generally of a few tens of nanoseconds. The DAC circuits have been designed with utmost care to obtain clean RF signals, with minimum spurious noise.

Data Sheet

On request USB Controller for PC, designed to drive 1 or 2 DDSPA through USB port (Windows XP/NT)


USB controller for DDSPA

This simple tool allows user to control its DDS driver thanks to its computer with a USB link. The provided software allows user to set manually frequency and power (option 8 bits) to the corresponding synthesizer (DDS).
