  • 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

    EMCTEST Tecnologia Eletronica e Telecomunicaçao Ltda.

    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.

Let Raymond RF help you design a chamber that will best fit your requirements.

  • 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.

  • Anechoic Test Chamber

    AntennaTesting.com

    The installation of our anechoic test chamber was completed by Orbit/FR in 2003. Our chamber measures 28' x 14' x 14' with 12" to 36" pyramidal anechoic absorbers and is fully shielded using a dual layer metal enclosure. Our test chamber is designed to for frequencies ranging from .700 to 6.00 GHz.

  • Shielded Anechoic Chamber

    Sahajanand Laser Technology Ltd.

    A total solution for Shielded Anechoic Chamber for performing measurements of antenna radiation patterns & RCS Measurement.The shielded chamber designed the by PAN design, which is a Total Steel Structure (TSS), an improved design over conventional sandwich type wood core structure (WCS) due to the reason like : Superior Attenuation with less weight and Easy expandability and relocation using less parts. TSS offers years of maintenance free, high RF attenuation. Project: (For Design & Specification Reference)Space Application Centre (SAC), Ahmedabad, India.

  • 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.

  • Anechoic Chamber room for Automotive components

    Microwave Factory Co,Ltd.

    Anechoic Chamber room of most suitable Automotive devices EMI/EMS test of the method of ALSE, which meet the global standard like a 2004/104/EC, several emmission standard like a CISPR25 which automotive manufacturers in EU/USA refer to, Immunity standard like a ISO11452 and others for the Automotive devices.

  • Electromagnetic anechoic box/Shield box/Anechoic chamber

    MICRONIX

    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.
