The MBX32CTR from Millibox is a mmWave & sub-THz compact antenna test range that operates 18 to 330 GHz. It has been designed to fit on a 6-foot lab bench and measures 161 x 112 x 83 cm. This compact chamber is suitable for mmWave and sub-THz OTA measurement with a quiet zone of 150mm.
The MBX32CTR test range includes an MBX32 chamber, a GIM04H-300E 2-axis positioner, a laser alignment system, a 300mm parabolic reflector, and a focus probe antenna. The probe and DUT wiring is done through the chamber deck and conveniently attaches to the measurement instrument placed in the two available bays. The test range is available from 18 to 54 GHz with coaxial wiring of the DUT and probe, while from 54 to 330 GHz, it is equipped with built-in VNA frequency extenders with wave-guide interfaces.
As this test range uses a parabolic reflector and a matching probe antenna placed at the focal point, the measurement distance between the probe and the DUT becomes virtually infinite and allows for RF measurements to be done using smaller chambers. It can support a DUT that weighs up to 1 kg and has a width of 150 mm.
