Anti-burnout and distortion-free circuit system in microwave high-power communication and application method

Abstract

The invention discloses an anti-burnout and distortion-free circuit system in microwave high-power communication. The circuit system is configured between an antenna and a post-stage receiving system,and the circuit system comprises a microstrip coupler connected with the antenna; a circulator, wherein a port A of the circulator is connected with the microstrip coupler, and a port B and a port Cof the circulator are respectively connected with a microwave switch A and a microwave switch B; a comparison control unit and a numerical control attenuation unit. The comparison control unit is connected with the microwave switch A, the microwave switch B and the numerical control attenuation unit through a matched driving circuit group; and one end of the microwave switch A is connected with ananti-burnout load chip. The invention provides an anti-burnout and undistorted circuit system in microwave high-power communication, which adopts a mode of combining a microwave switch with a load chip with preset power, so the system has a high-power anti-burnout function, and high-power undistorted transmission is realized through attenuation adjustment of a numerical control attenuation unit.

Description

technical field [0001] The invention relates to a device for use in the context of data communication. More particularly, the present invention relates to an anti-burnout and distortion-free circuit system and method of application for use in microwave high power communications used in radar communications and other wireless communications situations. Background technique [0002] In radar communication and other wireless communications, the reliability of microwave high-power communication is often encountered; in electronic warfare, ensuring the survival of one's own receiving system is the key to seizing electromagnetic control. [0003] In the prior art, in order to ensure the safety and effectiveness of communication, an anti-burnout limiter is set between the antenna and the subsequent receiving system, but the limiter cannot satisfy wide bandwidth and high power at the same time. Large dynamic distortion-free requirements, and in order to overcome this technical defe...

Problems solved by technology

[0003] In the prior art, in order to ensure the safety and effectiveness of communication, an anti-burnout limiter is set between the antenna and the subsequent receiving system, but the limiter cannot satisfy wide bandwidth and high power at the same time. Large dynamic distortion-free requirements, and in order to overcome this technical defect, the power of the post-stage receiving system can only be limited by setting up a server to meet the requirements of data transmission integrity and effectiveness, but the combination of the two The disadvantage is that the structure is complex, the cost is high, and it is not conducive to the later maintenance
