Abstract

The invention provides a measurement device and a measurement method for a folded waveguide traveling wave tube high-frequency system. According to the device and the method, a first clamp, a second clamp, a clamping base and a flange fixing member are utilized for fixing an energy transmission window and a folded waveguide slow wave structure, thereby facilitating connection and detachment between the energy transmission window and the folded waveguide slow wave structure. High testing precision is ensured, and furthermore detachment between the energy transmission window and the folded waveguide slow wave structure can be facilitated. No welding facility is required, and whole-set equipment discarding caused by non-qualification of a certain part is prevented.

Description

technical field [0001] The invention relates to the field of electric vacuum terahertz devices and the field of terahertz measurement, in particular to a measuring device and method for a folded waveguide traveling wave tube high-frequency system. Background technique [0002] As a wide-band, high-power, high-gain electric vacuum microwave amplifier, traveling wave tubes have been widely used in electronic countermeasures, radar systems, and satellite communications. The folded waveguide structure is a slow wave structure widely used in electric vacuum microwave devices, which has the advantages of large power capacity, flat dispersion, and large coupling impedance. After entering the terahertz frequency band, due to the size co-existence effect, the characteristic size of the slow-wave structure decreases, and the processing of the slow-wave structure generally encounters greater difficulties. Since the folded waveguide structure is well compatible with the MEMS process, th...
