Description
The LX5586 is a complete integrated 5GHz Front-End
Module (FEM) for an IEEE 802.11ac system. It includes
a highly linear 5GHz Power Amplifier (PA) with power
detector, Low Noise Amplifier (LNA) with bypass
capability, and SPDT antenna switch. This highly
integrated FEM only requires one bypass cap thus
reducing system footprint, bill of materials, and
manufacturing cost.
The LX5586 is available in a 16-pin low profile
2.5x2.5x0.4mm QFN Package.
