|Title:||High Spectral purity oscillator at 40 GHz: Design using air-dielectric Cavity|
|Published:||June 02, 2010|
|Abstract:||We describe the design of a low-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 using interferometric signal processing, (4) large operating signal power, approximately 1 Watt (W), and (5) relatively small size.|
