Review on Akozon Amplifier Noise 0 05 4GHz 0 6DB by Jonathan Unruh

I bought it to use as a 1090MHz ADS-B 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 if you intend to use it on a different frequency. P1dB/OIP3 rolls 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 filter although it says so in the description. )50MHz -8/17.5dBm500MHz 1.7/23dBm1GHz 6.5/22.8dBm2GHz 12.5/22.5dBm
