40dB Low Noise RF Amplifier

This low noise RF amplifier offers 40 dB of typical small-signal gain across an exceptionally wide 10 MHz to 6 GHz frequency span, with a noise figure of approximately 5 dB. Housed in a durable aluminum alloy chassis, it remains thermally stable during prolonged operation and resists external electromagnetic interference. Signal connections are made via high-quality SMA female connectors rated for 50 Ω impedance, while power is supplied simply and safely via a USB Type-C port requiring only 5 V DC. Included in the package are the LNA unit and its matched Type-C power cable. It is specifically intended for scenarios where signal integrity and sensitivity matter: enhancing weak FM radio broadcasts, strengthening GPS satellite signals in obstructed locations, supporting calibrated EMC measurement setups, and extending the dynamic range of software-defined radios used in spectrum monitoring or communications research. No configuration or tuning is required — it operates immediately upon power-up, making it ideal for rapid prototyping, educational labs, and field-deployable measurement systems.
