BGU8103UKAZ

射频放大器 SiGe:C LNA MMIC for GPS, GLONASS, Galileo and Compass

Overview

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.
