Low noise, hybrid tuned wideband voltage controlled oscillator

摘要

An oscillator comprising an active device having first, second and third terminals, a plurality of micro-stripline resonators coupled together to form a coupled-resonator network, the coupled-resonator network being coupled to the second terminal of the active device and a tuning network coupled to the coupled-resonator network, the tuning network being operable to adjust the coupling between at least two of the resonators that form the coupled resonator network.
