Abstract :
The relation between Q-factor and phase noise is verified in this paper. 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.
