Galileo
Rev. 4 — 6 May 2011
Product data sheet
1. Product profile
1.1 General description
The BGU7005 is a Low Noise Amplifier (LNA) for GNSS 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 0.85 dB. During high jamming power levels, resulting for example from a cellular
transmit burst, it temporarily increases its bias current to improve sensitivity.
CAUTION
This device is sensitive to ElectroStatic Discharge (ESD). Therefore care should be taken
during transport and handling.

Due to internal ESD diode protection, the applied voltage should not exceed the specified maximum in
order to avoid excess current.
The RF input and RF output are AC coupled through internal DC blocking capacitor.
