Review on Akozon Amplifier Noise 0 05 4GHz 0 6DB by Jennifer Wilson

I bought this to use as an ADS-B 1090MHz preamp. It uses LNA SPF5189Z and works as advertised. Gain and P1dB vary significantly with frequency as shown in the attached graph. This is useful to know if you plan to use it on a different frequency. P1dB/OIP3 drops off at lower frequencies, which can be a factor if you plan to use it in a high HF environment. This does not come with a screen or filtering, although the description says so. )50MHz -8/17.5dBm500MHz 1.7/23dBm1GHz 6.5/22.8dBm2GHz 12.5/22.5dBm
