摘要
This relates to a broadband injection-tuned Gunn diode microwave oscillator module. The module includes a Gunn diode and a microwave resonant cavity. The resonant cavity is a multi-tuned circuit to present the Gunn diode with its negative impedance over the requisite frequency band. The cavity is an evanescent mode waveguide. Tuning is accomplished solely by an injection locking signal which modifies the impedance of the cavity to match the Gunn diode over the requisite frequency band. This type of tuning eliminates the need for either electronic tuning of the Gunn diode and/or mechanical tuning of the cavity.
