In this letter, we report a low phase noise oscillatorexhibiting state-of-the-art phase noise characteristics at 60 GHz.The oscillator is stabilized by an off-chip substrate integratedwaveguide (SIW) cavity resonator, manufactured in LTCC technology.The area on top of the cavity resonator is used to flip-chipmount the MMIC, realized in SiGe technology. Measured oscillatorsdiscussed in this paper operate at frequencies of 59.91,59.97, and 59.98 GHz. The measured phase noise at 1 MHzoffset is 115.76 dBc/Hz, 115.92 dBc/Hz and 116.41 dBc/Hz,respectively. To our knowledge, the present hybrid oscillator hasthe lowest phase noise and highest figure of merit of integratedoscillators at V-band. The simulations are in very good agreementwith the measured oscillation frequencies.
