Abstract

The invention discloses a low-frequency and medium-frequency broadband power divider, which relates to the technical field of electronics and aims to solve the technical problems of narrow relative broadband, high insertion loss and poor phase uniformity of the conventional broadband power divider. An input end of the low-frequency and medium-frequency power divider is sequentially connected with a first micro-strip wire, a first wire-wound magnetic core, a second micro-strip wire and a second wire-wound magnetic core, two output ends of the second magnetic core are connected with a third micro-strip wire and a fourth micro-strip wire, an isolation resistor is arranged between the third micro-strip wire and the fourth micro-strip wire, and the other output end of the second micro-strip wire is grounded after being connected with a matched capacitor serially.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a magnetic core wire-wound broadband one-to-two power divider used in microwave communications, satellite communications, and electronic equipment. Background technique [0002] The broadband power divider is a power distribution component in the communication system and satellite receiving system, which realizes the function of frequency distribution. [0003] The existing medium and low frequency broadband power dividers generally have the following deficiencies: [0004] 1) Relatively narrow bandwidth; [0005] 2) Large insertion loss; [0006] 3) Phase consistency is poor. [0007] Contents of the invention [0008] The invention aims to solve the technical problems of relatively narrow bandwidth, large insertion loss, and poor phase consistency in traditional broadband power splitters, so as to provide a broadband power splitter with the advantages of wide freq...
