Aviation microwave anechoic chamber

Reference configuration

• Typical shield inner dimensions: 29m (length), × 14m (width), × 10m (height).

• Shielding structure: Smart Shield Twin Wall double-layer shielding structure, from the inside to the outside is high-performance composite conical absorber, anti-corrosion multi-layer board, shielding steel plate and standard shielding module, and between the two adjacent standard shielding modules, the conductive shielding liner Gasket is used for good RF shielding and electrical contact connection.

• Standard shielding module: 3m ×1m in size, made of 2mm thick double-sided hot-dip galvanized steel sheet with two bends on four sides. The thickness of the double-sided hot-dip galvanized steel sheet is ≥2mm, and the thickness of the galvanized layer is ≥20μm, and the thickness is uniform. The modules are connected by M10 screws with a high strength mark of 8 or more.

• Absorbing structure: high-performance composite conical truncated tip absorbing material EPP (can be selected according to needs), the ground can be laid with walkway panels, and the absorbing material can be covered with white reflectors for beautifying the internal environment and increasing brightness.

• Screen door: 1.2m×2m, 1.5m×2m, 2m×2m, 4m*4m and other sizes can be selected, and special size design can also be carried out according to needs, including manual, electric, pneumatic, and automatic track doors are available.

• Waveguide window: The standard size is 600mm×600mm (with flange), and the end frequency is 140GHz, which can be designed according to actual needs.

• Raised floor: the load is 2 tons/㎡, and the height is generally 30cm, which is consistent with the load capacity of the turntable.

• Filter: used for power supply 380V, 220V, 110V, DC, etc., as well as network, communication and other signal filtering.

• Video system: 2 sets of digital color surveillance system, one of which is fixed to the wall and 1 set of movable floor.

• Fire alarm system: adopts high-sensitivity air sampling and analysis system, which complies with the relevant regulations of the Ministry of Public Security of China on fire prevention products.

• Lighting system: halogen lighting, 1m above the ground illumination value of 250Lux, can be lifted
