Abstract :
High power radio frequency transmitters have been developed for the heavy ion linear accelerator of RIB project at VECC Kolkata. It works at 40 kW CW power in the frequency range of 32-39 MHz. The new approach of analysis and design of this transmitter has been carried out using ABCD matrix. It uses a linear small-signal AC model with input, output and inter stage matching circuits for Tetrode tube amplifier cascaded with Triode tube based diver amplifier. The analytical as well as measured S-parameter results are presented in this paper.
