Broadband RF preamplifiers are used during EMC measurements to reduce the effects of interference and noise. Preamplifiers are used to amplify weak electrical signals captured by antennas. During electromagnetic interference testing the preamplifier is usually located as close as possible to the antenna to reduce feed line losses. This active antenna positioning is often used in microwave systems, because coaxial cables suffer of high loss at microwave frequencies.
