Abstract

This paper describes the results of an experiment that tests a new high-power microwave amplifier concept that uses the virtual cathode phenomenon as an amplifier rather than as a free-running oscillator. The virtual cathode is surrounded by a cavity resonator that is driven by an input signal. The output from this virtual-cathode amplifier is frequency locked to the input signal, and exhibits amplification over at least a 10-dB dynamic range.
