The LX5589H from Microchip Technology is a 5 GHz 802.11ac Front-End Module (FEM). It has been designed to reduce the system footprint, bill of materials, and manufacturing cost. This module integrates a highly linear power amplifier (PA), log power detector, low noise amplifier (LNA) with bypass capability, and an SPDT Tx/Rx antenna switch. It supports 256-QAM modulation and operates over a channel bandwidth of 80 MHz. On the Tx side, this FEM delivers an output power of 20 dBm with a gain of 30 dB. On the Rx side, it provides a small signal gain of 12 dB and has a noise figure of 2.7 dB.
The LX5589H requires a DC supply of 5 V and consumes 150 mA of current on the Tx side and 10 mA of current on the Rx side. It is available in a 16-lead QFN package that measures 2.5 x 2.5 mm and is ideal for gaming, notebooks, mobile devices, access points, and tablet applications.
