Development of Solid State RF Amplifiers
With the use of Superconducting cavity, Solid State radio frequencies Amplifiers (SSA) are being considered for an increasing number of accelerator applications, both circular and linear, in kW level RF power regime. Their capabilities extend from a few kW to several hundred kW, and from few MHz to above 1 GHz. in particle accelerator, solid state high power RF source has drawn a considerable attention with the advent of SCRF cavity. Solid state RF source enjoys extreme modularity, simple maintenance, redundant design, and absence of high voltage power supply, easier maintenance, no warm up time, lower cost and simple start-up procedures. At RRCAT, SSA related activities were started for Indus-1 and Indus-2 RF system. Details of Solid state amplifiers development activities are described here.
