General description

The BGS8458, also known as the WLAN3101C, is a fully integrated MMIC Low-Noise

Amplifier and SP2T switch for transmit path. For WLAN applications in the 4.9 GHz to

5.925 GHz ISM band. Manufactured using high performance QUBiC eighth generation

SiGe:C technology of NXP.

The BGS8458 couples best-in-class noise figure, linearity, efficiency, low insertion loss

CMOS switches with the process-stability, and -ruggedness, that are the hallmarks of

SiGe:C technology.

The BGS8458 has a 1.2 mm × 1.4 mm footprint HX2SON6 package and a maximum

thickness of 330 μm.
