MAX2181：FM Automotive Low-Noise Amplifier
Highly Integrated FM Variable-Gain Low-Noise Amplifier Ideal for Use in Automotive FM and FM-Diversity
The MAX2181 is a highly integrated FM variable-gain low-noise amplifier ideal for use in automotive FM and FM-diversity active antenna applications. The device features an FM signal path, providing 30dB of gain range, controlled by an on-chip power detector. The FM signal path covers 76MHz 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, 3mm x 3mm, TQFN package and operates over the extended industrial temperature range (-40°C to +85°C).
