MAX2180A AM/FM Car Antenna Low-Noise Amplifier General Description The MAX2180A is a highly integrated AM/FM variablegain low-noise amplifier ideal for use in automotive active antenna applications. The device features separate AM and FM signal paths, each providing 30dB of gain range, controlled by individual on-chip power detectors. The AM signal path covers a 148kHz to 30MHz input frequency range, while the FM signal path covers 65MHz to 162.5MHz. The device integrates a voltage regulator and pass transistor, allowing operation using battery voltages in the +6V to +24V range. On-chip thermal protection automatically limits junction temperatures during extreme thermal conditions. The device is available in a small, 4mm x 4mm, TQFN package and operates over the extended industrial temperature range (-40ºC to +85ºC).
