MAX2181 Datasheet | Maxim Integrated

EVALUATION KIT AVAILABLE FM Automotive Low-Noise Amplifier General Description 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 30d B 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 (-40ºC to +85ºC). Applications - Automotive Active Antenna Features - +6V to +24V Supply Voltage Range - Integrated AGC Function Eliminates External Pin Diodes - High Dynamic Range - Low-Noise, Sub 3d B Noise Figure - Low External...
