2.10: Re-entrance

2.10 Re-entrance

Oscillators constructed with transmission line elements or resonators have re-entrant modes. For example, a half-wavelength resonator is also resonant at approximately odd multiples of the fundamental frequency. The open-loop cascade gain and phase should be examined at these higher resonances. If necessary, lumped reactive elements may be added to reduce the cascade gain to less than 0 dB above the desired oscillation frequency.
