The inductive output tube (IOT) continues to be the device-of-choice for terrestrial UHF broadcast applications due to its high efficiency, linearity, compactness, etc.; the same reasons that make this an attractive choice for scientific users. The IOT is being considered for a growing number of accelerator programs requiring multi-kilowatts of continuous wave power, at UHF and L-band frequencies. A number of vacuum electron device manufacturers are developing IOTs in support of these programs. There are an equal number of accelerator programs that operate pulsed, requiring high peak powers, where the only sources available are klystrons and MBKs. For these applications a higher-order mode IOT (HOM IOT) shows great promise for the same reasons described above. Modeling and simulation results for devices built to operate within the UHF and L-band frequency ranges will be shown, at power levels up to 5 MW.

A new generation of Inductive Output Tubes (IOT) have been developed with a focus on cost reduction, robustness, stability, enhanced power, improved gain and efficiency. As demonstrated with our L-band integral cavity IOT, a new family of IOTs can operate as CW or pulse amplifiers with up to 80 kW CW and 120 kW peak output power. Switching between the CW and pulse mode is easy and simple. In this paper, we will present our new compact designs and the latest performance data.
