Research on Efficient Testing of W-band High-power Sheet Beam Extended Interaction Oscillator

Abstract

The sheet beam extended interaction oscillator (SBEIO) is one of the miniaturized vacuum electronic devices that can provide high power output in millimeter wave and terahertz bands. In this paper, an experimental study of a high-power W-band SBEIO is carried out. According to its characteristics of high power and miniaturization, an experimental test scheme with adjustable mode and controllable stages was designed, and the WSBEIO was successfully operated in the 95 GHz frequency band with an average power of 2.05 kW for more than 1 hour, which verifies the reliability of the system and the high efficiency of the test strategy.
