mmWave and 77GHz automotive Radar anechoic test chambers. Designed by RF engineers for RF engineers.

Proudly presenting MilliBox from Milliwave Silicon Solutions, the first anechoic millimeter wave test chamber suited for wide deployment across the development organization. MilliBox is available in different sizes, MilliBox-2 (far-field distance 795mm), MilliBox-3 (far-field distance 1400mm) and MilliBox-4 (far-field distance 2050mm).

 

Effective layout & low loss wiring

MilliBox has instruments bays under the chamber to place a Spectrum Analyzer or Vector Network Analyzer on one side, and a Signal Generator or baseband board on the other side. It saves space and reduces loss due to long coax wiring.

 

No tangled wires

Wiring of the Device-Under-Test DUT is done with on axis pass-through channels to prevent cable tangling, and the DUT is mounted on the laser guided 3D gimbal rotating platform.

Open s/w interface and API

The 3D gimbal is controlled over a USB connection with open source software (source provided) containing all the functions, and an API for own test program development.

Open output format

MilliBox software run and plot a full spherical (or partial) radiation pattern graph up to 1 degree resolution (64000 points), saved as a time stamped Comma Separated Values (.csv) heat-map file listing all capture positions and corresponding captured data for easy post-processing in virtually every mathematics and graphic tools available on the market.

 

Millibox is highly cost-effective and optimal for real-life engineering work where daily iterations are needed, and many times in parallel tests and evaluations of new antennae design and RF performance in Radar and other mmWave applications.

3D GIMBAL (INCL CONTROLLER)

 

If you wish to build your own custom-size anechoic chamber, we can deliver the MilliBox 3D Gimbal as a stand-alone unit. MilliBox 3D Gimbal is ranging -180 to +180 degree in H and V planes, with a resolution of sub-1 degree in both planes. It’s ideal for a high-precision custom-designed anechoic chamber.

Motor control resolution better than 1 degree

Gimbal angle +-180 degree Horizontal, +-180 degree Vertical
