Abstract
Abstract An ultrahigh-frequency oscillator (10) stabilized by a dielectric resonator (20) comprising a housing (11) closed by a cover (12) and having a circuit (13) including a dielectric resonator (20) fixed in the bottom (14) of the housing (11). According to the invention, a small column (30) situated in the central part (15) of the housing (11) rigidly connects the bottom (14) of the housing (11) to the cover (12), the dielectric resonator (20) being arranged outside the said central part (15).
