Abstract

The invention provides a direct-current path integrated broadband strip-line combiner which comprises a cavity, a cover plate and a transmission wafer, wherein the bottom of the cavity body is provided with a plurality of teflon bases, the transmission wafer is arranged on the teflon bases, the two sides of the cavity are respectively provided with a connector, the transmission wafer is connected with the inner conductors of the connectors, and the cover plate is fixed on the cavity through screws. The combiner skillfully physically merges a direct-current path and a radio frequency channel together without an extra direct-current path. The combiner is simple in structure, easy to produce, small in volume, excellent in performance, and large in bearing power; and radio frequency and DC (direct current) share the transmission wafer without the extra direct-current path, and the transmission wafer is prepared through one-step forming, so that the combiner is low in cost, easy to machine, high in assembling efficiency, and suitable for mass production.

Description

technical field [0001] The invention relates to a broadband stripline combiner integrating a direct current path, belonging to the technical field of wireless communication equipment. Background technique [0002] The existing combiner is a passive device that can combine two broadband radio frequency signals into one and send it to the antenna with the minimum insertion loss. The combiner adopts distributed parameters and is realized through a mechanical structure. High, narrow bandwidth, requires an additional DC path. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a broadband stripline combiner integrating direct current paths. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] The broadband stripline combiner with integrated DC path is characterized by: it includes a cavity, a cover plate and a transmission sheet, and there ...
