NXP BGU8103X

The BGU8103 is, also known as the GPS1301M, an ultra low current and Low-Noise Amplifier (LNA) for GNSS receiver applications. The BGU8103 is available in a small plastic 6-pin extremely thin leadless package. The BGU8103 requires only one external matching inductor. The BGU8103 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 17.5 dB gain at a noise figure of 0.80 dB and a supply current of 1.2 mA. During high jamming power levels, resulting for example from a cellular transmit burst, it temporarily increases its bias current to improve sensitivity.
