Variable Frequency Drivers

Quanta Tech Sa propose 3 types of variable drivers:

The choice of a driver will be given by the type of AO device and will depend on the application purposes (commutation time, stability, accuracy…).

You can have a look in the RF application notes* to have informations on how to select the convenient driver.
