RF Preamplifiers
Preamplifiers, also known as preamps, take very weak signals and transmit them to standard amplifiers. They are ideal test instruments for enhancing measurement system sensitivity in EMC testing and other applications that call for low noise and high signal amplification. Troubleshooting and debugging as part of the radiated emissions portion of testing in particular often calls for RF preamplifiers to amplify signals otherwise immune to analysis.
Desirable qualities in preamplifiers include linearity (constant gain throughout range of operation), high input impedance (meaning only a negligible amount of current is necessary to sense an input signal), and low output impedance (stability in output voltage when current is drawn). Noise performance is also a key characteristic, as a signal needs to resist to be analyzed.
ATEC offers a variety of RF preamplifiers for rental with industry-leading rates from manufacturers such as AH Systems, Keysight, and Com-Power. Additionally, we can calibrate preamplifiers in-house to ISO 17025. Contact us for a quote today.
