This is a high performance filter and LNA combination for 1090 MHz ADS-B reception with 27dB of gain, a noise figure of around 1dB and over 60dB out of band attenuation. Designed to be used with bias tee power from our RTL-SDR Blog V3 dongles with the LNA mounted as close to the antenna as possible. It is triple filtered with a low loss high pass filter on the front end, and two 1090 MHz SAW filters placed in between and after the high performance low noise figure two stage MGA-13116 LNA. The triple filter design should help avoid dongle or LNA overload in noisy/strong signal environments.

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. Transmitting into or very close to the LNA may also cause damage.
