BGU8103UK数据手册恩XP中文资料规格书

描述 Description

The BGU8103UK is an ultra low current and Low-Noise Amplifier (LNA) for GNSS receiver applications. It comes as an extremely small and thin Wafer Level Chip Scale Package (WLCSP). This product is only used in an overmolded module. The BGU8103UK requires only one external matching inductor.
The BGU8103UK 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 18.5 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.
