Product Guide

mmWave Chambers
COMPACT- The device under test (DUT) antenna size andoperating frequency dictates the far-field distance requirement forover-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 ofthe 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, andextension “cubes” can be added later if the need arises.
The four top corners of the chamber feature passthrough access for accessories like air extraction, cameras, lights,or sensors. Other accessories, like sniffer mounts and fixed or oscillating trihedral corner reflector mounts, arealso available.

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.

MilliBox chambers come standard with a GIM01 3D DUT positioner, matching HOR01 horn post with WR2.2 to
WR15 horn clamp, power supply, USB dongle, and Python controller software. Other options are available.

mmWave Positioners
PRACTICAL- MilliBox offers several positioners for different DUT size andweight requirements. The positioners are built of high-performance printed PLA
biomaterial with low dielectric constant limiting stray reflections. The wiring tothe DUT is done using a passthrough in the horizontal and vertical bearings toprevent wire tangling during operation.

ACCURATE- A laser crosshair guide helps precisely align the initial DUT

boresight direction to the measurement horn. The real-time position control isachieved with the feedback of a built-in 12-bit absolute position encoder.

OPEN FRAMEWORK- MilliBox positioners are controlled over USB withPython software delivered in source. The software also controls any SCPIcompatible instrument connected by LAN, GPIB, or USB. All this helps toseamlessly integrate MilliBox into your existing RF testing environment. Manyradiation pattern types like HV plots or 3D plots come standard and can be easily
modified and augmented as desired.

OPTIONS- Standard horn clamp options are available for common waveguide sizes, and MilliBox can design andfabricate custom horn and DUT mounts, when needed. Design files of critical mechanical parts are available uponrequest to help you design accessories, mounts, or modify the original design.

GIM04: 3-Axis Positioners
GIM04 is MilliBox’s latest generation of mmWave and THz positioners. It can control 3 axes of rotation in Elevation,
Azimuth and Polarization from a single USB controller. Its construction allows GIM04 to adjust to various DUT formfactors. GIM04 adds a new level of versatility for daily over-the-air measurements.

POLARIZATION CONTROL- GIM04 positioners support thenew X-Pol platform system adding polarization as a 3rd axis to thedevice under test (DUT) control in addition to elevation and azimuth
axes.

ROBUST AND ACCURATE- All gears in GIM04 are made ofprecision machined DelrinTM material for higher strength, precsion andlong life span. GIM04 is equipped with smart actuators with absolute
encoders resolution below 0.1⁰.

ADJUSTABLE PLATFORM DEPTH- The DUT platform canbe placed at 2 depth from rotation axis: This makes is easier toaccommodate various DUT thickness and form factors.

MODULAR SIZE- GIM04 comes in 4 standard sizes all based on thesame components. Upsizing and downsizing is possible as DUT
requirements evolves over time.

CABLE ROUTING-To bring power, control or RF to the DUT
efficiently, GIM04 provides pass-thru channels at the center of eachrotation axis and numerous anchor points along the path. This way, noconnectors or slip rings are needed from source to DUT.

OPEN FRAMEWORK- As with all our other positioners, GIM04 iscontrolled by a Python based software provide in source which allows
easy integration with any instrument or DUT with several built-in
capture modes in multiple dimensions.

GIM05: Spherical Roll positioner
GIM05 brings a revolutionary solution for antenna over-the-air (OTA) mmWave and THz measurement with aspherical roll design offering the widest possible unobstructed field of view. Traditional Azimuth-Elevation positioners
have arm structures on the sides of the device under test (DUT) which blocks the measurement path at some highangles. Instead GIM05 holds the DUT from the back which completely clears the sides from obstruction and strayreflections coming from the positioner body.

ROBUST AND ACCURATE- All gears in GIM05 are made of
precision machined DelrinTM material for higher strength, precision andlong life span. GIM05 is activated by smart actuators with absoluteencoders resolution below 0.1⁰.

POLARIZATION CONTROLLER- The probe side is motorized
such that the probe can match the polarization of the DUT during therolling capture sweep. Also, it can also be programmed for any othercross polarization measurement.

MODULAR SIZE- GIM05 design allows the depth and the height tobe mechanically adjusted, to accommodate various DUT size
requirement. Two standard sizes are 340mm and 440mm representing
the maximum width of the DUT.

CABLE ROUTING-To bring power, control or RF to the DUT
efficiently, GIM05 provides pass-thru channels at the center of eachrotation axis and numerous anchor points along the path. This way, noconnectors or slip rings are needed from source to DUT.

OPEN FRAMEWORK- As with all our other positioners, GIM05 iscontrolled by a Python based software provide in source which allows
easy integration with any instrument or DUT with several built-in
capture modes in multiple dimensions.

Spherical Roll coordinates
GIM05 uses a new set of coordinates for its
rotation which eliminates the need for side arms.
This coordinate system can cover the entire
sphere around the DUT but the measurement
paths are different.

Typical Azimuth/Elevation
coordinates

Because the DUT is rotating on its radiation axis,
the measurement probe has to follow thepolarization of the DUT at all time to catpure
accurate measurement.
