Overview
IEC 60747-16-9:2024 is an international standard developed by the International Electrotechnical Commission (IEC). This standard defines the terminology, essential ratings, characteristics, and measuring methods for microwave integrated circuit phase shifters. These semiconductor devices are critical in systems where precise control of the phase of microwave signals is needed, such as in radar and advanced wireless communications. Adhering to this standard ensures interoperability, quality, and accurate performance measurement of microwave phase shifters across different manufacturers and applications.
