This item was taken from the IEEE Conference ' High spectral purity oscillator at 40 GHz: Design using air-dielectric cavity ' We describe the design of a low-phase modulated (PM) noise 40 GHz oscillator that uses a conventional air-dielectric cavity resonator as a frequency discriminator to clean up the PM noise of a commercial 10 GHz dielectric resonator oscillator (DRO) multiplied by four. The main features of this design incorporate (1) unloaded cavity quality factor (Q) of 30,000, (2) high coupling coefficient, (3) large carrier suppression by use of interferometric signal processing, (4) large operating signal power of approximately 1 Watt (W), and (5) relatively small size.
