Question 1: List at least two discriminations between the Klystron and TWT’s.
Question 2: Describe the problem of inter electrode capacitance and lead inductance of the wave frequencies.
Question 3: Describe the principle of TWT all along with neat sketch?
Question 4: Derive an expression for the maximum possible theoretical efficiency of a reflex Klystron.
Question 5: List two advantages of using Microwave frequency over low frequency?
Question 6: Define the term Transit time effect.
Question 7: What are the basic difference between Magnetron and TWT?
Question 8: Why at microwave frequency we talk of traveling waves with related powers rather than currents and voltages?
Question 9: What do you mean by velocity modulation? How is it distinct from normal modulation? Describe how velocity modulation is employed in klystron amplifier.
Question 10: What do you mean by slow wave structures? Describe how a helical TWT attain amplification.
