We present the new advances in ultra-stable microwave oscillators recently obtained at the department LPMO of the Institut FEMTO-ST Besançon. These microwave references are based on Sapphire Whispering Gallery Mode Resonators presenting high-Q factor. Different technologies have been developed with these resonators to fulfill the new requirements in term of phase noise or frequency stability for diverse scientific and technical applications.
