An application note “Receiver Front End Protection When Used with Active Antenna AAA-1″
AAA-1 active antenna has very high dynamic range and its 1 dB compression point is at +20 dBm. At the output a heavy clipped signal can reach 6 V pp. This voltage is safe for the most of the conventional receivers and transceivers. But the output voltage might be a problem for some receivers. Recently at the market several type of good SDR receivers are available ( SDR Play, Airspy, etc.) Most of them have a limitation of the maximal input signal at +10 dBm from the specification. This level is equal to 2 V pp. Read more ….
