9-4. A two-cavity amplifier klystron has the following parameters: Beam voltage: Beam current: Frequency: Gap spacing in either cavity: Spacing between centers of cavities: Effective shunt impedance: Determine: a. The electron velocity b. The de electron transit time V₁ = 900 V Io = 30 mA f = 8 GHz d 1 mm L = 4 cm Rsh = 40 ΚΩ c. The input voltage for maximum output voltage d. The voltage gain in decibels I wish to help me in solving this question this the reference book is Microwave Devices and Circuits Third Edition SAMUEL Y.
