This is a general purpose SPF5189Z based wideband LNA. Works from 50 MHz to 4 GHz with a noise figure of less than 1dB. Requires bias tee power, but there is an internal header which can be used to switch to external power, although for external power wires you’ll need to drill a hole into the enclosure. If you’re looking to improve ADS-B performance we recommend our Triple Filtered ADS-B LNA shown above.

Please note again: Requires 3 – 5v bias tee power. The RTL-SDR V3 provides 4.5v so is suitable.

IMPORTANT ESD NOTE: If you use this LNA placed close to an outdoor antenna, please ensure that your antenna is sufficiently grounded. There is a fast ESD diode, and GDT on the LNA PCB for protection, but if the antenna is not grounded the effectiveness of ESD protection components will be severely reduced, and you run the risk of damaging the LNA.
