As a guide to some of the important, yet often overlooked, aspects of mmWave phased arrays, we recently partnered with RFMW and Microwave Journal to produce an eBook covering components, testing, and critical requirements. The eBook features articles from Knowles Precision Devices (KPD) and other industry leaders, including Filtronic, Rohde & Schwarz, and MilliBox.
Rohde & Schwarz shares how they addressed the complexity of taking accurate OTA measurements by developing a compact antenna test range (CATR). Their solution uses multiple CATRs and has the capability to automate OTA measurements that require multiple angles of arrival. Finally, MilliBox reviews a flexible chamber solution that bridges the gap between traditional and DIY chamber solutions without breaking the budget.
