Abstract

The invention discloses a high-power waveguide load comprising a connection flange, a transition cavity, an absorber, a rear cover plate, and a radiator. The transition cavity is connected with the connection flange and the radiator. The rear cover plate is connected with the end, away from the transition cavity, of the radiator. The absorber, which is arranged in the cavity of the radiator, includes a first rectangular ceramic absorbing sheet, a second rectangular ceramic absorbing sheet, a first tapered ceramic absorbing sheet, and a second tapered ceramic absorbing sheet. The sides of the first rectangular ceramic absorbing sheet, the second rectangular ceramic absorbing sheet, the first tapered ceramic absorbing sheet and the second tapered ceramic absorbing sheet are in closed connection, and the absorber obtained after connection is hollow inside. On the basis of satisfying the requirement for high power of the waveguide load, the machining difficulty of the absorber structure is reduced, and the machining efficiency and the precision of overall assembly are improved.

Description

technical field

[0001] The invention belongs to the technical field of waveguide loads, and in particular relates to a high-power waveguide load. Background technique

[0002] The main function of the matching load is to absorb the incident power of the microwave system as a single-port component, which is widely used in microwave technology devices. In the military aspect, it has been used more and more in the fields of radar, electronic countermeasures, satellite communication, rocket telemetry and remote control, and high-frequency testing. In terms of civilian use, it has also been widely used in mobile communications, cable television, satellite navigation, etc. The matching load can usually be divided into three types: low power, medium power and high power according to the level of withstand power. According to the different transmission lines, it can be divided into coaxial load, waveguide load and microstrip load.

[0003] The basic structure of the high-power wav...
