With the Q-DRIVER concept QUBIG offers dedicated RF systems which match and enhance the features of all free-space resonant modulators. Digital frequency synthesis allows precise frequency and phase control. An integrated resonance lock (Q-Lock) working up to 19GHz automatically finds and subsequently tracks the fre- quency of the modulators which ensures an operation at optimal efficiency. Together with the automatic frequency drift compen- sation (F-Lock) QUBIG’s RF drivers have become a plug & play sys- tem where only two input parameters need to be adjusted: the de- sired frequency and modulation depth.
QUBIG’s Q-Drivers are also suited for traveling wave modulators. Dedicated digital synthesiser modules with signal bandwidths from 20MHz up to 8 or 19GHz are conform with the bandwidth performance of the EOMs. Depending on the application, broad- band RF amplifiers with an output power up to 10W within a frequency range of several GHz must be properly chosen for the respective application.
Q-Drivers are based on a sophisticated modular concept that al- lows flexible and easy adaptation to a wide variety of applications by simply plugging in functional modules in a slot card interface. The basis driver module contains besides a digital frequency syn- thesiser all necessary components (power supply, RF amplifier, user interface, various interlock functions etc.) for a standalone opera- tion. For convenient system integration, besides the hardware QUBIG also allows to control/communicate with the driver remote- ly by PC via a Python interface.
