Pre-amplifiers boost weak RF signals before they reach a receiver or spectrum analyzer, improving measurement sensitivity during EMC testing. They are used across conducted and radiated emissions setups where additional gain is needed without significantly raising the noise floor.
Browse pre-amplifiers from leading manufacturers below. Filter by frequency coverage and company to compare models. Each listing includes gain, noise figure, and other key specifications.
