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.
