    摘要： Disclosed is an encapsulated micro-diode and a method for producing same. The method comprises forming a plurality columns in the substrate with a respective tip disposed at a first end of the column, the tip defining a cathode of the diode; disposing a sacrificial oxide layer on the substrate, plurality of columns and respective tips; forming respective trenches in the sacrificial oxide layer around the columns; forming an opening in the sacrificial oxide layer to expose a portion of the tips; depositing a conductive material in of the opening and on a surface of the substrate to form an anode of the diode; and removing the sacrificial oxide layer.

    摘要： A radio-frequency amplifier includes at least two double-ended electron discharge devices in coaxial-type, radio-frequency cavity-resonator circuits. Each discharge device has a discharge region so that the amplifier comprises a plurality of longitudinally spaced-apart, electrically connected discharge regions. Each of the discharge regions has a cathode with an anode circumscribing the cathode. At least one grid electrode is disposed between the cathode and the anode. A coaxial input transmission line is loop-coupled to an input cavity-resonator circuit and a coaxial output transmission line is loop-coupled to an output cavity-resonator circuit.
