1.1 General description
The BGU7258 is a fully integrated MMIC Low Noise Amplifier (LNA) for wireless receiver
applications in the 5 GHz to 6 GHz ISM band. Manufactured in NXPs high performance
SiGe:C technology, the BGU7258 couples best-in-class gain, noise figure, linearity
and efficiency with the process stability and ruggedness that are the hallmarks of SiGe
technology. The BGU7258 features a robust temperature-compensated internal bias
network and an integral bypass / shutdown feature that stabilizes the DC operating
point over temperature and enables operation in the presence of high input signals,
while minimizing current consumption in bypass (standby) mode. The 1.6 mm x 1.6
mm footprint coupled with only two external components, makes the circuit board
implementation of the BGU7258 LNA the smallest IEEE 802.11ac LNA with bypass
solution on the market, ideal for space sensitive applications.
