- 14 - ABSTRACT OF THE DISCLOSURE VERY HIGH FREQUENCY OSCILLATOR WITH GYROMAGNETIC RESONATORS The invention relates to a very high frequency oscillator (4 - 22 GHz) having two YIG ball resonators. The oscillator according to the invention based on a field effect transistor,has two YIG balls, whose resonant frequen- cies are displaced, which gives it a wide frequency band. Moreover, one of the two balls is doubly coupled to the source and gate of the transistor, which gives the oscillator is characterized in that one YIG ball is doubly coupled to the source and gate of the transistor, which gives the oscillator a good linearity (=10-3) in the frequency band. The oscillator is characterized in that one YIG ball is doubly coupled to the transistor and in that one of the two coupling wires, namely that connected to the transistor gate, is doubly coupled to the first and second balls. Application to ultra-high frequency equipment.
