Abstract

The invention discloses a traveling wave tube slow wave system, a traveling wave tube including the traveling wave tube, and a traveling wave tube transceiver assembly. The slow-wave system includes a helix, and a first port for inputting a signal to be amplified respectively coupled with the helix; a second port for outputting the amplified signal and a return signal from the receiving antenna; a second port for outputting the received signal Three ports, the third port is arranged between the first port and the second port and close to the side of the first port. Compared with the prior art of the traveling wave tube slow wave system including two energy transmission ports, the traveling wave tube slow wave system provided by the present invention adds a receiving signal output port, which can realize the integrated function of sending and receiving signals of the traveling wave tube , which simplifies the cascade structure of existing T / R components, promotes the miniaturization of information processing equipment, and reduces its production cost; at the same time, it effectively avoids the impact on the overall system due to the performance limitation of high-power switches, and improves system performance and reliability. sex.

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 ...
