General description
The BGS8424 is, also known as the WLAN3101H, a fully integrated MMIC low-noise
amplifier, and SP3T switch for Bluetooth path and transmit path. For WLAN applications
in the 2.4 GHz to 2.5 GHz ISM band. Manufactured using the high performance QUBiC
eighth generation SiGe:C technology of NXP.
The BGS8424 couples best-in-class noise figure, linearity, efficiency, low insertion loss.
Also the CMOS switches with the process stability and ruggedness are the hallmarks of
the SiGe:C technology.
The BGS8424 has a 1.5 mm × 1.5 mm footprint HX2SON8 package and a maximum
thickness of 330 μm.
