Bringing Precision to Measurements for mmWave 5G Wireless
Catherine A. Remley
At millimeter-wave frequencies and for wide modulation bandwidths, the hardware performance of both modulated-signal sources and vector receivers becomes increasingly nonideal. These nonidealities make test and validation of devices, circuits and systems not only more important, but also more difficult. This is especially true because future systems will likely push the limits of modulation complexity and bandwidth to increase data throughput. We will discuss calibration and measurement techniques to correct millimeter-wave modulated-signal measurements illustrating that traditional assumptions at microwave frequencies may not be adequate at millimeter-wave frequencies.
