IP3

IP3, or third-order intercept point, is a technical measure used in radio and communications equipment to evaluate how well a device handles strong signals without distortion. It predicts the point where the combined effects of two signals would produce an undesirably high level of distortion if the device could handle such power. A higher IP3 indicates better linearity, meaning the device can process multiple signals simultaneously with less interference and distortion. This measurement helps engineers assess and compare the performance of amplifiers and receivers, ensuring reliable communication in complex signal environments.
