Advances in solid-state magnetron modulation
Abstract
Recent advances in solid-state magnetron modulator technology are surveyed that have made new options available to system designers. Solid-state modulators have been developed to drive magnetrons directly and through pulse transformers. These modulators are based on arrays of inexpensive standard power MOSFETs, but have properties associated with high power hard tubes. The direct drive units are used to drive injection-locked magnetrons and small weather radar magnetrons for test and characterization purposes. A transfer coupled unit, implemented at the brassboard level, drives a magnetron at up to 1 MW of RF output with good detected RF pulses and spectra.
