Integra Systems, Inc., will be authoring a series of blogs describing the value of an antenna in a wireless solution. This includes embedded, WLAN, and DAS. As these designs become more and more complex the value of a low PIM requirement is not only desired but required. PIM (passive intermodulation) is a form of intermodulation distortion that occurs in components normally thought of as linear, such as cables, connectors and antennas. However, when subject to the high RF powers found in cellular systems, these devices can generate intermodulation signals -80dBm or higher.
