PIM Test Power Level

In order to promote measurement consistency, IEC 62037 currently recommends that components used in mobile communications systems be tested using 2x 20 Watt (43 dBm) test tones. This recommendation has served the wireless industry well through the development and deployment of 2G and 3G systems. With the more stringent requirements of 4G and 5G systems, demand for higher linearity (lower PIM) construction is needed. With this need, it is time to reassess the historical test power level recommended by IEC 62037 and determine if 40 Watt (46 dBm) test power might better serve modern mobile communications networks.
