Description

technical field [0001] The invention belongs to the field of amplifiers, and in particular relates to a broadband expansion interaction amplifier circuit. Background technique [0002] Vacuum electronic devices are widely used in military and civilian fields, and have continuously growing application requirements in systems such as radar, communication, security imaging, biomedicine, aerospace, and electromagnetic energy weapons. It is true that vacuum electronic devices are challenged by solid-state devices in the application of low frequency, low power and narrow bandwidth, but thanks to their special working mechanism, vacuum electronic devices can be used in high frequency, high power, high efficiency and wide bandwidth, etc. advantages are particularly prominent. If the vacuum electronic amplifier can further improve the efficiency and bandwidth in the millimeter wave and terahertz bands, it will have a greater competitive advantage in comparison with solid-state devic...
