Description
The BGU8011 is a Low Noise Amplifier (LNA) for GNSS receiver applications, available in
a small plastic 6-pin extremely thin leadless package. The BGU8011 requires one external
matching inductor and one external decoupling capacitor.
The BGU8011 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 16.3 dB gain at a noise
figure of 0.65 dB. During high jamming power levels, resulting for example from a cellular
transmit burst, it temporarily increases its bias current to improve sensitivity.
