MBX33 – mmWave anechoic chamber

MBX33 mmWave anechoic chamber for radar test

8ft large capacity mmWave anechoic chamber

MBX33 is an innovative mmWave chamber which fits on a 10ft lab bench. Because it is made out of 30″ cubes instead of the standard 24″ cube of MBX0x series, it provides more volume on the inside. This can be important in several situations, for example when the DUT is large in size or when testing mmWave radar with trihedral corner reflectors. 

This version has 3 instrument bays to place spectrum analyzer or vector network analyzer just below the measurement deck, therefore saving space and reducing loss due to long coax wiring.

MBX33 presents all the benefits offered by the MBX0x series but because of its size it can accommodate several custom options especially related to mmWave radar target tracking. For instance a popular customization consist of installing corner reflector targets in pattern on the opposite wall. Additionally, the installation of smart linear actuators activating radar targets can make a very compelling setup. Contact us directly if you want to find-out more about our customization options.

MBX33 is suited for 186cm far-field measurements
