Check out the Open Source Radio Telescopes Project. They use our Red LNA with a bias-tee in their Amplifier Box B.
Spectrum Scanning Projects

Jon has some spectrum scanning projects in which he uses our LNA and FM notch filters. It's interesting how he puts them into die-cast boxes. This is something we get asked about all the time. You can read about the projects here and here. Jon's wireless projects are definitely worth reading about.
FM reception using the 40 dB LNA and HackRF

David Goldstein sent in a few pictures that show FM reception without and with the 40 dB LNA. A significant gain in performance with the LNA. Thanks David!
Considerations when using high-gain LNAs
Posted by GPIO Labs on
Some of our LNAs provide in excess of 40 dB of gain and operate over a wide frequency range. The primary application of these products is to amplify weak signals by increasing the signal-to-noise ratio at the receiver.
