At present, the testing frequency of shielded boxes is mostly concentrated between 300mhz-3Ghz. At present, ultra-low frequency and ultra-high frequency radio frequency products are also increasing, which puts forward new requirements for the shielding effect and test processing methods of shielding boxes. The shielding box uses conductive or magnetic materials to make shields of various shapes such as shells, plates, sleeves, etc., to limit the electromagnetic ability to a certain space range to suppress radiation interference with metal bodies, and to process conduction and radiation to achieve benefits. The tested wireless communication equipment provides non-interference test environment equipment,
The structure of the pneumatic shielding box:
1. Shielding effectiveness: above 70DB.
2. It is suitable for high-frequency function test of mobile phones, cordless phones, walkie-talkies, wireless network cards and other products.
3. Install coaxial connectors and data interfaces according to customer requirements, and mount absorbing materials to prevent residual wave interference.
4. Internal dimensions: length 300*width 330*height 250 (mm).
5. Using aluminum alloy die-casting structure, small size and light weight.
6. The inclined opening form is convenient for product access and jig making.
7. Double-cylinder control is used to enhance the closing force, improve the shielding effectiveness and production efficiency.
8. Measurable frequency: 900MHZ-5.8GHZ.
