Question

he parameters of a two-cavity amplifier klystron are as follows: Beam voltage: Beam current Vo 1200 V lo-28 mA Frequency; f 8 GHz Gap spacing in either cavity: Spacing between the two cavities: L4 cm Rsh40 k2 (excluding beam loading Effective shunt resistance: a. Find the input microwave voltage Vi in order to generate a maximum output voltage V2 (including the finite transit-time effect through the cavities). b. Determine the voltage gain (neglecting the beam loading in the output cavity c. Calculate the efficiency of the amplifier (neglecting the beam loading). d. Compute the beam loading conductance and show that one may neglect it in the preceding calculations.
