Abstract

The invention discloses a low-loss high-isolation miniaturized double-broadband combining dividing filter, comprising a main body, a first cavity, a second cavity, a first resonant column assembly, a second resonant column assembly, a first interface, a second interface, and a third interface. The first resonant column assembly comprises a plurality of resonant columns arranged in sequence, and a connecting component is arranged between adjacent resonant columns. The second resonant column assembly comprises a plurality of resonant columns arranged in sequence, and a connecting component is arranged between adjacent resonant columns. The first resonant column assembly is arranged in the first cavity, and one end of the first resonant column assembly is connected with the first interface, and the other end is connected with the third interface. The second resonant column assembly is arranged in the second cavity, and one end of the second resonant column assembly is connected with the second interface, and the other end is connected with the third interface. The connecting components are arranged between the resonant columns of the combining dividing filter, so as to increase bandwidth to satisfy improve requirements of ultra wide band of the filter.

Description

technical field [0001] The invention relates to the technical field of filters in the communication field, in particular to a low-loss, high-isolation, miniaturized dual-broadband combining and splitting filter. Background technique [0002] In today's mobile Internet era, almost all operators around the world face the problem of operating 2G / 3G / 4G multi-standard networks at the same time. Converged network construction is the general trend of mobile network operations. For more than 30 years, after the development of 2G, 3G and 4G, my country has accumulated millions of single-mode single-frequency base stations (BBU, RU, RRU). How to make full use of these precious equipment resources to achieve continuous and deep coverage of remote multi-mode, multi-frequency, and multi-standard is another more economical, realistic and technically more complex problem that operators are currently facing. To this end, the industry has proposed various solutions and means, such as multi-...
