ABSTRACT:
The disclosed microwave distributed amplifier includes a plurality of cascaded field emission triodes, each having a field emission element for emitting electrons, a grid disposed downstream from the field emission element along the electron flow path and an anode disposed further downstream along the electron flow path. A series of inductive strips interconnect successive grids to form a grid transmission line, while another series of inductive strips interconnect successive anodes to form an anode transmission line. Small electron transit times over integrated circuit distances in a vacuum environment and low interelectrode capacitance allow extremely large gain-bandwidth products to be achieved.
