Abstract:The analysis methods for the steady‐state responses of the mm‐wave band NRD‐guide negative impedance oscillators based on nonlinear microwave autonomous circuits harmonic balanced method are presented in the paper in details. Firstly, the large‐signal nonlinear lumped equivalent circuits of the Gunn diode are studied in mm‐wave bands. Then, the performances of two kinds of NRD‐guide autonomous circuits, the probe‐exciting LSM11o‐mode oscillator and the LSE11o‐mode oscillator, are analyzed by the way of extracting the large‐signal dynamic harmonic admittance (conductance) of the Gunn diode or directly configuring the harmonic balance equations for the oscillator. The input impedance of the exciting probe in the oscillator and the performances of the load‐pulling and the local stability of the NRD‐guide oscillator are also involved.
