High power RF pulses at a frequency of up to 1 GHz have been produced using a fully solid state system that consists of a gyromagnetic NLTL and a solid state pulse forming circuit. The novel sgyromagnetic NLTL and a solid state pulse forming circuit. The novel solid state SOS diode-based driver produces sub-10ns pulses of the order of 100 kV. The pulse generator is capable of running at pulse repetition frequencies from 100 Hz continuous up to 2 kHz in burst mode, with a rise-time of a few nanoseconds. The gyromagnetic NLTL is a solid state RF source that consists of an oil-insulated coaxial transmission line, which is loaded with ferrite cores and housed within a solenoid electromagnet coil. The solenoid is used to apply a DC bias to the ferrite material to control the level of RF generation. The system has been operated at peak RF power output levels of around 90 MW. We present details of the pulse generator, the gyromagnetic NLTL, diagnostics, calibration methods and performance of the system. We also compare the results to predictionsolid state SOS diode-based driver produces sub-10ns pulses of the order of 100 kV.
