mmWave and 77GHz automotive Radar radiation pattern chambers. Designed by RF engineers for RF engineers.

MmWave Test Solutions proudly present 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 795 mm), MilliBox-3 (far-field distance 1400 mm) and MilliBox-4 (far-field distance 2050 mm). Because the MilliBox system is modular, a MilliBox-2 can be expanded to a MilliBox-3 or 4 with one or two extension modules.

Effective layout and low loss wiring

MilliBox has instruments bays under the chamber. Hence, a spectrum analyzer or vector network analyzer can be placed on one side. A signal generator or a base-band board can be placed on the other side. As a result space is saved and loss due to long coax wiring is reduced.

No tangled wires

The Device-Under-Test is wired with on-axis pass-through channels to prevent cable tangling. In addition, 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) that contains all the functions. In addition an API for own test program development is included.

Open output format

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

Affordable and portable

Millibox is highly cost-effective and optimal for real-life engineering work where daily iterations are needed. MilliBox can be used in parallel tests and evaluations of new antenna design and RF performance in Radar and in other mmWave applications.

3D GIMBAL 01 (INCL HW CONTROLLER AND SOFTWARE)

Gimbal 01

 Gimbal 01

The MilliBox 3D Gimbal is a stand-alone unit you can use, if you wish to build your own custom-size anechoic chamber.

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.The max DUT is 11 cm width, 4 cm depth, 20 cm height and a weight of 500 grams.

Motor control resolution better than 1 degree

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