Abstract
An electronic device for amplifying microwave or millimeter wave signals. A microwave or millimeter wave input signal stimulates a gated field emission array to produce a density modulated beam of electrons containing about 1 billion to 1,000 billion bunches or pulses per second which in turn illuminates a thin diamond target in a diamond switch connecting a load to a high voltage source. Each electron in each pulse creates a large number of electron hole pairs in the diamond. The high voltage bias across the diamond causes most of the very large number of pairs to be swept through the diamond target producing a high current surge in less than one half the period of the designed output frequency. Induced RF currents are set up within the resonant output cavity in response to the current flowing within the diamond. In summary, each surge of current produces an electromagnetic pulse at the load. Thus, an electromagnetic millimeter wave is produced with a frequency equal to the frequency of the signal output.
