Analysis of the possibility of performing microminiature low-voltage electron devices for vacuum millimeter-wavelength integral circuit

The output characteristics of a strip distributed microwave (MW) power amplifier tuned by voltage in a wide frequency range analyzed. New energy collector designs are proposed to be employed in the amplifier in the form of a periodically nonuniform strip line and electron optical system comprising an electron gun with the multi-edge field emitter array current modulator. Their electrodynamic and current parameters have been calculated by rigorous methods. The analysis of the output amplitude-frequency characteristics of the amplifier was performed. It is shown that, unlike the previously reported amplifier design, it can allow for a higher gain in the short-wavelength region of centimeter band, including the millimeter band, or operate at substantially lower beam currents.© (1994) COPYRIGHT SPIE--The International Society for Optical Engineering.
