Welding, two outlet ends angle circumferentially of the power splitter with line B is 180 degree.
When work, entrance input of the signal from power splitter with line B, by power splitter band line B, after signal is divided into two, respectively
Becket A is reached by metallic rod A and metallic rod B.Becket A is placed in annular media slot, but becket A and annular
Media slot does not contact, distance about 0.5mm~1mm.And it is 25 medium, such metal that annular media slot, which selects dielectric constant,
Ring A passes through annular media slot and becket B generates close coupling, i.e. the signal of becket A is coupled on becket B.Energy
It is coupled to after becket B, is transferred on power splitter band line A from metallic rod C and metallic rod D respectively, by power splitter band
The energy of line A synthesizes, the entrance output signal from power splitter with line A.
By way of the media slot of high dielectric constant and metal loop coupling, solve VHF frequency range contact disc type joint makes the present invention
With the problem that the service life is shorter, reliability is poor.By proper choice of metal cavity size, can make joint 50MHz~
Within the scope of six octave of 300MHz, for standing wave less than 2, insertion loss is less than 1dB.Entire joint structure is simple, and processing cost is low
It is honest and clean, small volume, and also debugging work load is minimum, and it is basic after processing is completed not have to debug and directly use.In addition the pass
It is larger to save intermediate space, therefore intermediate space can be made high-power coaxial joint, at the same the joint can add up stacking formed it is more
Road joint.
