MAX2180 - AM/FM Car Antenna Low-Noise Amplifier

General Description

The MAX2180 is a highly integrated AM/FM variable-gain low-noise amplifier ideal for use in automotive active antenna applications.

Key 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 +8V to +24V range. On-chip thermal protection automatically limits junction temperatures during extreme thermal conditions. The device is available in a.
