Low noise crossed-field amplifier

摘要

In a forward wave low noise cross-field amplifier a slow wave structure is disposed about a predetermined portion of the cathode. The slow wave structure of the cathode is accurately proportioned and spaced to have a dispersion curve near to the dispersion of the slow wave structure of the anode to permit cross-coupling of the RF input from the slow wave structure of the anode to the slow wave structure of the cathode.
