BGU8309Z

RF Amplifier BL Smart Antenna Solutions

Overview

The 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.

The 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.
