Although Q-factors in oscillator circuits can be calculated by input impedances of the oscillator circuits and their frequency-derivations, the numerical calculation accuracy may be degraded when the impedance locus for frequencies drastically shifted. To improve the calculation accuracy, the reflection coefficient having values from -1 to 1 was focus on in calculation procedure. First, the Q-factor formulae based on the immittance and the reflection coefficient were derived and the usefulness was evaluated. In the results, it was confirmed that the Q-factor formula based on the reflection coefficient has a good convergence performance for the increment in numerically-frequency derivation procedure. By using this calculation technique, Q-factors of the self-injection locked NRD guide Gunn oscillator were calculated. |
