  • Anechoic Chamber

    Jumho Electric Corporation

    Wedge:The acoustic absorptivity of sound-absorbing materials used in anechoic chamber must be greater than 0.99. In anechoic chamber, gradient absorption layer, wedge or conical structure are often applied with glass wool and flexible foam as its sound-absorging materials. Anechoic Door: The design of rotatable door can affect the whole function of anechoic chamber. Therefore, it's crucial to combine steel plate and sound-absorbing cotton in the door, which is exactly our design.Acoustic Insulating Material:Applying high-density materials to enclose external noise. Damping materials: Using spring, rubber and cotton to enhance damping capacity.The Anechoic Chamber conforms to GB/T 6882-86 and ISO 3745 specifications.

  • Anechoic chambers


    The anechoic chambers are built up as a modular construction. Due to individual modules any size of chamber can be manufactured. Big chambers may require an outer supporting structure or alternatively the shielding material can be attached direct to the building. The absorbers are fixed to rails bars or wooden base construction which is inserted into the shielding modules.

  • Anechoic Chamber

    Beijing KeHuan Century EMC Technology Co,.LTD

    (7m × 4m × 3m) RF shielding EMC laboratory (anechoic chamber) is constructed by attaching ferrite tiles and microwave absorbing materials after the RF shielding room is built (7m × 4m × 3m) The simple 3m test distance EMC laboratory can perform EMC tests in the frequency range of 30MHz-18GHz.

  • Anechoic Chambers

    Eckel Noise Control Technologies

    Anechoic Chambers are echo-free enclosures with a sound energy absorption level of 99% to 100%, or a reflected sound pressure level of 10% or less. The frequency at which the energy absorption drops below 99%, or the pressure reflection exceeds 10%, is known as the low-frequency cut-off. Sound absorption is obtained by lining the walls, ceilings, and floor with wedges or other sound absorbing elements or SuperSoft panels, depending on performance level required and cut-off desired.

  • Anechoic Chamber

    EMC-3 - MVG EMC

    A 3 meter test range ensuring fully compliant Emission and Immunity testing. Ferrite and hybrid pyramidal absorbers are combined in a unique pattern within a SmartShield high performance chamber. Operating at a 3m test distance, this chamber is compliant to CISPR-16 with a measurement zone diameter of 1-2 meters.

  • Tapered Anechoic Chamber

    Cuming-Lehman Chambers

    It’s nearly impossible to perform VHF/UHF measurements in a rectangular chamber. In the 1960’s Emerson determined that tapering one end of an Anechoic Chamber would cause the chamber to act like an indoor ground reflection range.Tapered Chambers work very well at the lower frequencies. Their design forms a uniform illumination across the test region. The tapered end of the chamber forces the wall images close together forming a source antenna array. Tapered Chambers are usually a less expensive option compared to rectangular antenna measurement chambers or compact ranges.

  • Compact Anechoic Chambers

    MilliBox Original

    If you have mmmwave or THz antenna phased-array that require Over the Air measurements, MilliBox has the equipment and tools that you need. With the help of MilliBox compact anechoic chamber system, you can plot radiation pattern , collect data from those plots, and assess your antenna performance easily and precisely.

  • Anechoic Chamber Filters

    Adaura Technologies

    RF leakage through Ethernet and USB cables can destroy even the best RF enclosures and chambers. The need for filtering in the ever congested RF environment requires special filters that can pass USB 2.0 and 10/100/1000 Mbps Ethernet signals and filter out unwanted higher frequencies such as cellular and WiFi. The Adaura Technologies USB/Gigabit Filters provide one GigE and one USB 2.0 pass-through connections while filtering out other RF up to 8GHz. It has a small form factor to allow easy installation. It is a most cost effective solution for a clean chamber set up. In a typical chamber, WiFi signals are reduced to <-100dBm with this filter installed.

  • Electromagnetic anechoic box/Shield box/Anechoic chamber


    The necessity of a wireless system test has risen by the spread of recent wireless telecommunication equipment as shown in cellular phone, wireless LAN, RF-ID tag and ETC (Electronic Toll Collection system). It is necessary for a wireless test to be performed in anechoic environment in which an external noise is intercepted and a radio wave does not reflect internally. An anechoic chamber (room version of a shield box) is proper facilities but needs a wide space and a huge cost. Especially, the equipment under wireless system test on the production line can not radiate any signal radio wave outside before approval. The shield box satisfies these conditions.

  • Large-size Hybrid Reverberation / Anechoic Chamber

    F-Series - Emite Ingeniería SL. Ed

    The F large-size hybrid Reverberation/Anechoic Chamber represents the most versatile OTA test system in the market today. With the same unique test features of their E Series RC counterparts, the F-Series can also test large form-factor devices under test (DUTs) like laptops, large TV sets, solar and trash compactors, drones, fridges or washing and vending machines, among others. With up to 16x16, 8DLCC and DUTs up to 2m and 500 kg including full-body phantoms in a turntable, the F Series also expands the frequency range down to cover 200 MHz up to 40 GHz frequency ranges and the test modes to include EMC, BS, small cell, eNodeB and Virtual Drive Testing over the air (VDT-OTA). In an again unheard-of feature, the F-Series is also reverse-convertible into an Anechoic chamber, allowing Far Field (FF) and Spherical Near Field (SNF) radiation patterns, efficiency and gain measurements and pre-5G testing of antennas and devices. Conversion from RC to AC or vice versa can be performed within half a day.
