MBX3x – 30″ section modular anechoic chambers for mmWave and sub-THz antenna testing

COMPACT– The device under test (DUT) antenna size and operating frequency dictates the far-field distance requirement for over-the-air (OTA) testing and drives the chamber dimensions. At mmWave frequencies, the far-field dimension is small enough so that MilliBox chambers can comfortably fit on a lab benchtop.

The deck has multiple measurement positions with 8cm (3”) passthrough holes for direct wiring without connector ports. Conveniently, measurement instruments can be placed just below the MilliBox chamber deck, which reduces the RF coax length and cable loss.

The horn post and the DUT positioners are placed on opposite ends of the chamber deck. Access to the inside is granted through the front doors that close to seal the chamber during test.

MODULAR– MilliBox chambers are built of modular construction components allowing the creation of several configurations to address differing needs. The MBX0x series is made of 60cm (24”) cubic modules and the MBX3x series of 80cm (30”) cubic modules. The chamber size is selected to satisfy your far-field requirements, and extension “cubes” can be added later, if the need arises.

AFFORDABLE– Compared to “Do-It-Yourself” systems, MilliBox are complete solutions that are priced advantageously, offer better performance, and do not waste scarce engineering resources to develop and maintain.
