App note: AM/FM active antenna

An introduction to AM/FM active antennas: [via]

This article is a reference design (RD) for an automobile AM/FM active antenna. The RD presents the flexibility of the MAX2180 active antenna low-noise amplifier (LNA) and shows how to set the AM and FM gain and the automatic gain control attack point. Single and dual antenna schematics are detailed, including the input and output matching circuits. Using this design together with the data sheet and device’s evaluation (EV) kit, a prototype antenna can easily be developed for a wide range of active antenna requirements.
