🔍 Key Concepts

• Gunn diode oscillators and how they generate microwave frequencies • Difference between an active device (the diode/semiconductor) and a frequency-determining network (like a resonant circuit or cavity) • Role of a resonant cavity in selecting and stabilizing the oscillation frequency

💭 Think About

• Which part of the oscillator actually sets or selects the oscillation frequency, and which parts only influence power level or stability? • Does changing the power supply voltage or load normally change the designed operating frequency, or just the amplitude/efficiency? • What component in most RF and microwave oscillators is specifically designed to have a natural resonant frequency?

✅ Before You Answer

• Identify which option describes a tuned or resonant structure rather than just a bias or material property • Think about what would happen to the frequency if you changed only the supply voltage while leaving the physical structure the same • Consider how resonance is normally implemented at microwave frequencies (lumped LC vs. waveguide or cavity) and match that to one of the options
