BGU8309 is, also known as the GPS1401M, a low current Low Noise-Amplifier (LNA) for GNSS
receiver applications. The BGU8309 is available in a small plastic 5-pin extremely thin
leadless package. The BGU8309 requires only one external matching inductor and is
optimized for higher IP3i performance.
BGU8309 adapts itself to the changing environment resulting from co-habitation of
different radio systems in modern cellular handsets. It has been designed for ultra low
power consumption and optimal performance when jamming signals from co-existing cellular
transmitters are present. At low jamming power levels, it delivers 17 dB gain at a noise
figure of 0.65 dB and a supply current of 3.6 mA. During high jamming power levels,
resulting for example from a cellular transmit burst, it temporarily increases its bias
current to improve sensitivity.
