SiGe:C Low Noise Amplifier MMIC for GPS, GLONASS, Galileo
and Compass
Rev. 1 — 31 January 2014
Preliminary data sheet
1. Product profile
1.1 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.
