Broadband 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.

The EMC Shop carries preamplifiers from top Brands like:

A.H. Systems

Com-Power

Teseq (Schaffner)

and more!!

  • 100 Hz - 1 GHz

    Clean up the signal going into your spectrum analyzer, EMC receiver or other meter by using a preamplifier and identify the troublespots that may be buried in the noise. Preamplifiers that fall into the frequency range of 100 Hz to 1 GHz.

  • 1 GHz - 40 GHz

    Clean up the signal going into your spectrum analyzer, EMC receiver or other meter by using a preamplifier and identify the troublespots that may be buried in the noise. Preamplifiers that fall into the frequency range of 1 GHz - 40 GHz.
