Description
Technical field
The utility model relates to a kind of ultra broadband power splitter.
Background technology
Power splitter is one road input signal energy to be divided into the output of two-way or multichannel equates or the device of unequal energy, also is the Primary Component of communication system, and along with the progress and the development of science and technology, fields such as the communication technology are also more and more higher to the requirement of power splitter.Power splitter in the market mainly is divided into two types of cavity power splitter and microstrip power dividers, the cavity power splitter mainly is applied to indoor covering system separately, and microstrip power divider is because the less frequency band of power is narrower, generally do not use separately, in order to realize the wide frequency antenna coupling, often use two microstrip power dividers, realize the low frequency coupling for one, realize the high frequency coupling for one, debugging has brought very big influence but this gives production.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of ultra broadband is provided, the high isolation, and miniaturization, low-loss, continuous working period is long, the ultra broadband power splitter that adaptive capacity to environment is strong.
The purpose of this utility model is achieved through the following technical solutions: the ultra broadband power splitter, it comprises housing and circuit board, housing is provided with input port and output port, circuit board places in the shell cavity, the one side of circuit board is furnished with microstrip circuit, described microstrip circuit is made of the microstrip line section of two groups of symmetries, every group of microstrip line section is by the little band impedance conversion of one-level line, the little band impedance conversion of secondary line, three grades of little band impedance conversion lines, the little band impedance conversion of level Four line, the little band impedance conversion of Pyatyi line, six grades of little band impedance conversion lines, seven grades of little band impedance conversion lines and eight grades of little band impedance conversion lines connect to form successively, the bending of microstrip line section is arranged on the circuit board, be provided with the isolation resistance that is used to isolate between two groups of microstrip line sections, described housing zoarium is silver-plated, circuit board adopts low-loss RT5580 material, and the microstrip line section surface is gold-plated.
The beneficial effects of the utility model are:
1) the utility model adopts the mode of eight grades of little band cascade technology and microstrip line bending wiring, has realized the ultra broadband of power splitter, the high isolation and miniaturization;
2) the utility model adopts low-loss RT5880 material as circuit board, and the microstrip line section surface is gold-plated, makes the product loss lower;
3) the utility model material simple and durable, continuous working period is long, and adaptive capacity to environment is strong.
