Preliminary data sheet
1. Product profile
CAUTION
1.1 General description
The BGU7005 is a Low Noise Amplifier (LNA) for GPS receiver applications in a plastic
leadless 6-pin, extremely small SOT886 package. The BGU7005 requires only one
external matching inductor and one external decoupling capacitor.
The BGU7005 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 optimal performance when jamming signals from co-existing cellular
transmitters are present. At low jamming power levels it delivers 16.5 dB gain at a noise
figure of 0.9 dB. During high jamming power levels, resulting for example from a cellular
transmit burst, it temporarily increases its bias current to improve sensitivity.
This device is sensitive to ElectroStatic Discharge (ESD). Therefore care should be taken
during transport and handling.
