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.
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 +8V to +24V range.
On-chip thermal protection automatically limits junction temperatures...
