Advantages
Higher electron emission currents for the same applied voltage are often desirable for increased efficiency in vacuum tube power amplifiers. The improved MEMS design provides this additional benefit by incorporating the electron multiplying structure.
Furthermore, feedback control can be incorporated in the device, providing a novel means to tune the spacing of the cathode to gate separation (or other component spacings).
Detailed Description
Researchers at UC San Diego have invented a design and method of fabrication for a vacuum microtube device used for cold-cathode microwave amplification. This MEMS design and practical fabrication method provides for precise and consistent spacing of the cathode, grid, and anode and does not require the extra micromachined features (flaps, notches, hinges, etc.) required for mechanical release (flip up) operations for assembly and maintenance of the three dimensional configuration.
