Broadband preamplifiers are used during EMC measurements to reduce the effects of noise and interference. 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.
The different high gain preamplifiers we offer cover a frequency range up to 40 GHz. Our EMI preamps designed to have flat gain with minimal variations over the whole operating frequency range. High gain and low noise figures of our preamplifiers help improve overall system sensitivity significantly, resulting in accurate EMC measurements.
During electromagnetic interference (EMI) measurements, preamplifiers are very effective in measuring low level signals. Although our preamps are primarily intended for EMC applications, it may be used for other applications that require low noise and high signal amplification.Features:
* Preamplifiers can be used with power adapter or battery pack (included).
