BGU8004RF/IF射頻/中頻RFID的射頻放大器規(guī)格書PDF中文資料

General description

The BGU8004 is a Low Noise Amplifier (LNA) for GNSS receiver applications. It comes as extremely small and thin Wafer Level Chip Scale Package (WLCSP). The BGU8004 requires one external matching inductor.

The BGU8004 adapts itself to the changing environment resulting from co-habitation of different radio systems in modern cellular handsets. It has been designed for low power consumption and optimized 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 0.60 dB. During high jamming power levels, resulting for example from a cellular transmit burst, it temporarily increases its bias current to improve sensitivity.
