ABSTRACT:
A modulator with improved damping comprises a charging network which limits the rate at which energy is transferred into a pulse forming network, and a switch to discharge the energy stored in the pulse forming network when the network has charged to a predetermined energy level. The pulse forming network discharges into the primary winding of a transformer which couples the energy to its secondary winding which routes the energy to an RF power generating tube. The modulator also includes an improved damping network which places a diode and resistor electrically in parallel with each other, and both in series with the switch to reduce the magnitude of the post-pulse voltage oscillations.
