Improving Transmit/Receive Module Test Accuracy and Throughput

Phased arrays have been used in radar applications for many decades. Recent trends are driving their adoption into other applications such as Electronic Warfare (EW), satellite systems, and even 5G communications. There are several new component technologies that are driving this migration: multiple transmit/receive (T/R) modules on a chip, higher-performance PCB laminates, and the acceptance of GaN as a power amplifier (PA) semiconductor process.
