AR8188
Low Noise Amplifier for FM



 
Product Overview
The AR8188 is a high gain, low noise amplifier (LNA) for FM applications. It operates from 2.2V to 3.6V and achieves 18 dB gain and 1.5 dB noise figure while giving a high linearity.
 
The current consumption of AR8188 in enable mode and disable mode are 6mA and 0.05uA respectively. The AR8188 is in a very small, SOT363 6-pin package. It requires low bill of materials, including one external matching inductor, one bypass capacitor and one DC blocking capacitor. The AR8188 is the best solution to improve the FM receiving performance obviously and easily.
