The embodiment of the invention discloses a spatial power synthesizer. The spatial power synthesizer comprises a spatial power synthesizing module, an output module, an input module, copper strips anda grounding line; the input end of the spatial power synthesizing module is connected with the input module; the output end of the spatial power synthesizing module is connected with the output module; the copper strip is wound around the joint of the input end of the spatial power synthesizing module and the input module; the copper strip is wound around the joint of the output end of the spatial power synthesizing module and the output module; and the shell of the spatial power synthesizer is connected with the grounding line. According to the spatial power synthesizer provided by the embodiments of the present invention, the copper strips are wound around the joints of the input end and output end of the spatial power synthesizer and the spatial power synthesizing module, so that a relatively shielded environment can be formed in the spatial power synthesizer; the shell of the synthesizer is connected with the grounding line; and therefore, an ideal grounding effect can be realized, and therefore, a self-excitation problem caused by the insufficient processing precision of structural parts or the non-closed fitting of the assembly of single clamping components during radio frequency power space synthesis can be solved.
Description
technical field [0001] The invention relates to the field of space power combining, in particular to a space power combining device. Background technique [0002] The technology of using multiple antenna units to emit electromagnetic waves with the same frequency and phase in accordance with a specific relationship, so that they are superimposed and synthesized during space propagation, so as to form electromagnetic beams in a certain direction is called space power combining technology. The power amplifiers of the space power combination work in parallel, and the signals of each way are propagated to the air through the low-loss waveguide for combination, which has a high combination efficiency, so it has been widely used. [0003] Due to the high-frequency electromagnetic waves of the space power combiner, the requirements for grounding are relatively high, and often in the process of processing, due to the low machining accuracy of the structural parts, the bonding betwee...
