BWant Adopts Anritsu ME7868A Modular Vector Network Analyzer to Achieve OTA Performance Testing for Phased Array Antenna System with High Dynamic Range

Anritsu Corporation announces a collaboration with BWant Co., Ltd. (BWant) to verify the performance of beamforming systems used to measure phased array antennas. These tests adopt Anritsu ME7868A modular vector network analyzer (VNA) and are verified on BWant's MW6 OTA (Over-The-Air) chamber platform, which can be applied to the performance related tests for Low-Earth Orbit (LEO), base stations, mobile phones, Wi-Fi 6E and Ultra-Wide Band (UWB) antenna systems.

Anritsu's ME7868A is the world's first modular dual-port vector network analyzer (VNA) that consist of two MS46131A 1-port VNAs, and is available in 8/20/43.5 GHz frequency ranges and 2/5/25 meters in length. With supporting patented PhaseLyncTM synchronization technology, the ME7868A can separately perform full dual-port S-parameter measurements over a distance of 100 meters or more, which simplifies and improves the S-parameter measurement architecture. Its flexibility also simplify the configuration between DUT and ME7868A VNA port, reduce the Cable Loss and improve Dynamic range and measurement stability by eliminating the need for long cables.

"Anritsu provides the ideal test solution for our MW6 phased array OTA anechoic chamber technology," said Kelvin Chiu, General Manager of BWant. "Anritsu ME7868A modular dual-port VNAs addresses the issues as optimizing the OTA test system, because the required cable distance to device under test (DUT) and feed antenna are shorter than previous system structure, which also improve the cost and stability of the MW6 measurement system. In addition, the MW6 system integrates with anti-twist and 3D-CATR, which can accurately and quickly measure the beam chart of the phased array antenna, which reduce research and development time of phased array antennas for R&D engineers.”

"Anritsu offers a comprehensive range of test solutions that fully supports 5G, satellite communications and mmWave product development. We are honored by BWant’s continued trust, and verify the advanced functions implemented on its devices. In the fiercely competitive market, with stable and high-quality testing technology, we will take the lead in mastering the key capabilities of product development, and jointly drive the OTA industry progress for 5G and satellite communications,” said Ivan Chen, General Manager of Anritsu Taiwan.

About BWant

Founded in early 2012, BWant has adhered to the insistence of “The more precise measurement our OTA systems are, the better wireless communication system our customers could develop” focusing on the user experience as key direction of product design, and customized the software and hardware interface designs according to the needs of each customer. In addition, BWant devotes to developing practical OTA systems which improves the R&D efficiency of antenna for engineers. Since 2017, BWant had launched M-series mmWave OTA measurement systems, in addition to existing sub-6 GHz OTA products, and jointly evaluate feasible solutions for 6G OTA with many academia-industry collaborations. Whether AiP, smartphone, laptops, routers, active antenna module (AAU) and LEO antenna arrays, BWant can provide the total solutions.
