Cell phone jammer has the same function as the suppressor

If the waveguide itself with a flange, the use of waveguide flange to be fixed to the shield, the need to shield flange and base gasket installed between the electromagnetic shield design used in most of the cutoff waveguide to the number of Honeycomb has. cell  phone  jammer is also known as the cell phone interference unit.Honeycomb is the principle of a large number of cut-off waveguide welded together to form the cut-off waveguide array, which can form a large open area, and to prevent leakage of electromagnetic waves. Since the cut-off here is a hexagonal cross-section waveguide, much like the formation of cellular arrays, so called honeycomb panel.
3.4 Application of honeycomb panels
Aluminum honeycomb panel bonding material and metal (steel, copper, etc.) welding two. Aluminum honeycomb is bonded to a layer of aluminum foil layer bonded together according to certain rules, and then opened the form.   cell  phone  jammer   can also be called breaker.This material previously used in aircraft wings, so many places can be produced. But it is worth noting that this material can not be directly used for electromagnetic shielding. Because each cell of the surrounding conductive discontinuities. In practical engineering, will see a lot of this material is applied directly. This shielding effect is used when the poor. Because the original cellular material, the electrical connection between the cellular unit is leaning process due to "errors" between the cells causing cellular "short" form, and it's very random. Electromagnetic shielding to use this material on the metal coating process must be carried out using the metal coating around each cell to form a continuous conductive layer. cell  phone  jammer has the same function as the suppressor.Commonly used metal coating process is electroless plating, metal is generally nickel. This high cost of plating, after plating the cell often cost close to the metal plate welded honeycomb panels. U.S. SPIRAL company invented a special processing technology, can solve the problem of conductive aluminum honeycomb, while maintaining a low cost, we will provide in the next article. Aluminum honeycomb panel bonding strength is another problem, when there is a strong external force to the cellular material, it will damage the cell. Therefore, in using this material to the attention of the appropriate protective cellular network outside the installation.   cell  phone  jammer   acts according to the same principle as that of cropper. Metal plate welded honeycomb panel is an ideal shielding material, it is not the shortcomings of aluminum foil honeycomb panels, high shielding effectiveness. Although many foreign literature indicates that the high cost of this material, but in view of the cost of domestic aluminum plating is also higher, compared with aluminum honeycomb panel this drawback is not very prominent. Keli Yate manufactured board in metal welding cell is close to the cost of aluminum foil honeycomb panel. Commonly used honeycomb panel thickness is 1 / 2 inch of edge of unit cell size is generally l / 8 "(3.18mm), 3 / 16" (4.76mm).
Use of honeycomb panel materials problems that need attention around the same honeycomb panels overlap with the problem of shielding the substrate.   cell  phone  jammer   is the same as the isolator.This involves two lap points, a honeycomb panel core is the overlap with the border, border and shield the other is the overlap matrix.
