5 GHz ISM SiGe:C low-noise amplifier MMIC with bypass

Rev. 2 â 30 October 2014

Product data sheet

1. Product profile

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 NXPâs 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 ï´ 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.
