Embodiment Construction

[0020] Such as Figure 4 and 5 As shown, the present invention includes a base plate and a cover plate 5, and the cover plate 5 is covered on the base plate. After the two are covered, the upper end surface of the cover plate 5 is provided with three load ports, and the peripheral contact edges of the two are fixed by welding. It can effectively prevent the leakage of microwave energy in the case of transmitting high-power microwave signals, so as to avoid the interference of microwave signals on equipment or harm to human body.

[0021] Five signal ports are arranged around the periphery of the welding of the two, and the base plate includes the first, second, and third magic H units and a connection block, and the connection block is arranged between the three magic H units, and four Or gapless integrated design; the magic H unit described in this application is the basic unit, but it will be appropriately changed according to the needs when it is specifically combined, tha...

Abstract

The invention discloses a microwave high-power distribution / combination device. The microwave high-power distribution / combination device comprises a bottom plate and a cover plate; the bottom plate is covered with the cover plate; after the bottom plate is covered with the cover plate, the upper end surface of the cover plate is provided with three load ports, and the periphery of the cover plate is provided with five signal ports; the bottom plate includes a first magic H unit, a second magic H unit, a third magic H unit and a connecting block, wherein the connecting block is arranged among the three magic H units, and the four components are arranged in an gapless and integrated manner. According to the microwave high-power distribution / combination device of the invention, based on a microwave high-power capacity structure magic H, the three magic H units are combined together to form a structure shaped like a Chinese character "pin"; the magic H structure is fed into the same waveguide through two transmission lines connected together, so that branch line couplers which have two different work modes are coupled; after simulation optimization design and sample piece processing and debugging are performed on the parameters of the structure, the structure can be applied to a deep space exploration microwave high-power amplifier; and when the structure performs microwave power output, the air breakdown risk of cascaded filters can be lowered, and high-quality spectrum high-power microwave signals can be obtained.

Description

technical field [0001] The invention relates to the technical field of high-power microwave applications, in particular to a microwave high-power distribution / synthesizer. Background technique [0002] With the advancement of global informatization, a large amount of information needs to be transmitted through radio frequency and microwave communication equipment. With the increase of transmission distance, higher requirements are placed on the output power of microwave transmitters. On the one hand, due to the In order to obtain higher microwave power, it must be realized in the form of power distribution / combination. On the other hand, in order to improve the spectrum quality, it is necessary to process the high-power microwave signal with a filter. Due to the power capacity of the filter itself in the case of high power There are limitations, and the high-power microwave signal needs to be distributed first, then processed by a filter, and then power-combined, so as to ob...
