Abstract
An active YIG oscillator driving device is comprised of: an YIG oscillator including a main coil, an FM coil, a frequency generator operating to generate an output frequency in response to a magnetic field generated from the FM coil; a phase locker setting the output frequency to a target frequency by controlling an amount of current provided into the FM coil and adjusting the output frequency; and a main coil controller regulating the amount of current provided into the main coil, if the output frequency varies out of a controllable range by the FM coil, and adjusting the output frequency. A time for setting the output frequency of the YIG oscillator is shortened to improve the stability of the output frequency thereof against environmental conditions.
