According to the phase noise model proposed by D.B. Leeson in 1966, it estimates about a 6 dB reduction in phase noise as Q-value of resonator doubled. By fabricating three substrate-integrated waveguide cavity oscillators on different substrates with different Q-values, we could obtain the same tendencies between measurements and computed values from the proposed model and thus verified the relation between Q-factor and phase noise. © 2005 IEEE.application/pdf383398 bytesapplication/pdfCavity resonators; Gain control; Oscillators (electronic); Spurious signal noise; Waveguides; Phase noise; Q-factor; Substrate-integrated waveguide cavity oscillators; Signal noise measurementconference paper10.1109/APMC.2005.16067842-s2.0-33847101481
