Faraday Cages | Professional RF Test Enclosures and Shielded Rooms

 

LBA EMFaraCage® faraday cages are EMI and RFI shielding boxes and RF test enclosures which bring convenience to device testing. The faraday cage is ideal for isolating critical systems in high field RF environments, or wherever RF ingress or egress must be minimized. Security, production testing, biomedical research, and semiconductor testing are only a few of the many areas where EMFaraCage® faraday shielded enclosures are employed.

EMFaraCage® faraday cage enclosure systems are fully featured to support a wide variety of test missions. The standard faraday cages include effective power, dataline, and RF signal isolation in a large test volume. The EMFaraCage® faraday cages are much more affordable than shielded room solutions, and with the convenience of portability.

Customized EMFaraCage® Faraday Cages

Most customers have specialized requirements. Thus, LBA Technology regularly custom designs and fabricates EMFaraCages® faraday cages for a wide variety of applications. We will quote you the faraday cage enclosure that exactly suits your application. The photos above show just a sampling of the specialized configurations we have produced.

Shielded rooms and Architectural RF Shielding

If more than an EMFaraCage® faraday cage is needed, LBA has a long experience in providing FaraCage® shielded rooms and architectural building RF shielding, and will work with you to produce the EMI RF shielding result you require!

LBA also sells shielding paints and shielding fabrics for architectural shielding projects.

Notes on EMFaraCages® Performance:

EMFaraCage® faraday cage RF test chambers provide excellent radio frequency shielding in the range of 10 kHz to 6 GHz.

The electrical field shielding is very high down to typical AC power line frequencies of 50 – 60 Hz, but the standard aluminum EMFaraCage® faraday cage looses its magnetic shielding effectiveness at these lower frequencies. For applications requiring good magnetic shielding, options include steel construction of the faraday cage, or providing an inner lining of material such as mu-metal.

High frequency performance is largely determined by penetrations, power, and I/O provisions.

The standard shielded enclosure system is designed with waveguide below cutoff ventilation ports and fiber optic entry ports sized for maximum effectiveness below 6 GHz. LBA strongly recommends using fiber for all USB, Ethernet, or other communication I/O’s. At low RF frequencies, the system is much more tolerant of cabled connections, which will, nevertheless, deteriorate electromagnetic shielding effectiveness.

Where RF I/O is required, systems can be furnished with specialized gland plates mounting most bulkhead connector types such as “N”, BNC and SMA. RF connectivity must be tightly controlled to ensure no ingress or egress of the very radio frequency signals the EMFaraCage® faraday cage is being employed to block!

Access panels can be equipped with viewing windows. The impact of the windows on shielding effectiveness (SE) is a function of window type, size, and frequency. A typical 15 cm x 15 cm window will have little impact at 100 MHz, but deteriorate SE by 20 dB or more at 6 GHz.

Device under test (DUT) powering is also an important consideration. A frequently employed option is the AC power filter. These filters have little impact on the SE through 6 GHz. The ideal situation would be to use only internal batteries to power the DUT and ancillaries. DC power can also be supplied through appropriate filters. In systems with viewing panels, the lighting option of choice is an LED wall mounted battery light.

 

Using EMFaracages®  for Protection Storage

Police and investigative agencies are faced with preserving and protection electronic devices or the data within them from intentional or unintentional compromise by radio frequency radiations. The LBA Technology EMFaraCage® is a convenient, radio frequency secure storage enclosure for evidence room or laboratory. It is effective against RF frequencies to over 6000 MHz, and HEMP, solar flare and power line electrical fields. The EMFaraCage® RF shielded enclosures may be configured for storage only, or with filtered power and data connections for use in evidence testing or “black hat” functions requiring isolation from external RF fields.
