mmWave Test Solutions, a manufacturer of modular anechoic chambers and positioning solutions for over-the-air antenna measurements, has introduced the DUO3.5 and DUO5.5, two new high precision positioners in the DUO series. 

The DUO 3.5, an evolution of the DUO3, introduces a sliding device under test (DUT)/antenna under test (AUT) arm to adjust DUT depth easily. By clever use of a bracketing arm system, the DUO3.5 allows rapid changes between DUTs of varying depth without needing DUT plate adapters or spacers. In addition, the DUO3.5 broader arm base will hold DUTs/AUTs up to 30 cm in width. 

The new DUO5.5 offers a sizeable capacity increase over the DUO5. The DUO5.5 can hold DUTs up to 83 cm width, making it ideal for testing antennas in large mechanical enclosures such as automotive side-view mirrors with radar sensors, vRAN/OpenRAN base station antennas, or gNodeB units with non-centered antenna placements.

“The new DUO 3.5, and impressively sized DUO5.5, are built upon our existing portfolio of positioners and share the same DNA and quality,” said Christian Petersen of mmWave Test. “The high precision components and CNC-machined structures will guarantee long-lasting rigidity and performance required in professional test applications.” 

The DUO3.5 and the DUO5.5 are available immediately and ship worldwide.
