Oscillator electronically tunable within a very wide frequency band |
摘要 |
An oscillator of the "three-terminal" type, comprising for example a field effect transistor, having a narrow spectrum and electronically tunable within a very wide frequency band in spite of its narrow spectrum due to a resonator of the yttrium garnet ball type. The field effect transistor has its source connected to a dipole comprising an electronically variable reactance and its gate connected to a similar dipole. A feedback loop is also established between input and output circuits of the oscillator. Under the action of a single command, acting for example on a magnetic field, the reactances vary simultaneously. In one embodiment, a single yttrium garnet ball resonator has two conductive half loops inserted in the tuning dipole and coupling dipole of the oscillator.
