The H-Series OTA CATR + DFF + SNF (0.6/3 GHz to 40/67/110 GHz) Test Ranges provide complete 3D performance assessment for 5G devices and antennas including gain, efficiency, directivity, polarization and beam characteristics for frequencies from 0.6 up to 110 GHz, capable of supporting forthcoming 5G Sub-6 GHz (from 600 MHz to 6 GHz) and mmWave (24 to 110 GHz) standardized testing in accordance to 3GPP TR38.810, TR37.842 and TR38.101. The nature of 5G Sub-6 GHz and mmWave frequencies makes OTA testing extremely sensitive to physical positioning and to phase and gain measurement accuracy, and for this reason aerospace-used technology has been incorporated into our H-Series chambers. With serrated reflectors providing unique 15µm peak-to-peak roughness in 36 cm quiet zone and high accuracy 0.03° positioners, with both roll over azimuth and roll over elevation, the H-Series are undoubtedly a best-in-its-type set of chambers, and the only ones in the market capable of testing FR1 Sub-6 GHz and FR2 mmWave frequencies in a simultaneous manner. Additionally, an optional climatic enclosure allows for OTA testing under controlled temperature and humidity conditions.
