Abstract

The invention discloses a combiner for ultra-wideband wireless communication. The combiner comprises a high-frequency port, a lower-frequency port and a combining port, wherein a high-frequency band filter is arranged between the high-frequency port and the combining port; and a low-frequency band filter is arranged between the low-frequency port and the combining port. The combiner is characterized in that the high-frequency band filter and the low-frequency band filter are interdigital cavity filters. The combiner has the advantages that: the combiner is realized by two interdigital cavity filters, so that the defects that filters such as a micro-strip filter, a dielectric filter and the like have small power capacity, low intermodulation, large insertion loss and the like can be overcome, the defect that a coaxial comb filter has narrow bandwidth also can be overcome, and 70 percent of bandwidth can be realized maximally.

Description

technical field [0001] The invention relates to a combiner, in particular to a combiner for ultra-wideband wireless communication. Background technique [0002] In engineering applications, it is necessary to combine and output two or more RF signals in different frequency ranges. Using a combiner, a set of indoor distribution system can work in multiple frequency bands at the same time. At present, the combiners on the market mainly include microstrip combiners, comb combiners, etc. Among them, microstrip combiners have problems such as low power and large insertion loss; comb combiners have frequency band Narrower, larger volume and other issues. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a combiner for ultra-broadband wireless communication with wide narrow band and small volume. [0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a combi...
