Abstract

The invention discloses a traveling wave tube slow wave system and a traveling wave tube comprising the same, and a traveling wave tube transceiver module. The slow wave system includes a spiral line,a first port used for inputting a signal to be amplified, a second port used for outputting the amplified signal and receiving an antenna return signal, and a third port used for outputting the received signal, wherein the ports are coupled to the spiral line, and the third port is arranged between the first port and the second port and near the first port. Compared with the traveling wave tube slow wave system containing two energy transmission ports in the prior art, the traveling wave tube slow wave system provided by the invention is additionally provided with a received signal output port, the signal transmitting and receiving function of the traveling wave tube can be achieved, the cascade structure of the existing T/R module is simplified, the miniaturization of information processing equipment is promoted, and the production cost is reduced. Moreover, the influence of the performance limitation of high-power switches on the whole system is avoided, and the system performance and reliability are improved.

Description

technical field [0001] The invention relates to the technical field of microwave vacuum electronics. More specifically, it relates to a traveling wave tube slow wave system, a traveling wave tube including the traveling wave tube, and a traveling wave tube transceiver assembly. Background technique [0002] The transmitting / receiving component (T / R component) is an indispensable core component in the phased array radar system, and the T / R component plays a key role in the performance and reliability of the entire system. The T / R component not only has the power amplification function of the transmitted signal, but also has the amplification and return of the received signal. As an electric vacuum device with radio frequency power amplification function, the traveling wave tube is usually used in the transmitting unit of the T / R module as the final power amplification. [0003] T / R components composed of traveling wave tubes in the prior art, such as figure 1 As shown, it ...
