Smallest WLAN Power Amplifier For Handsets And Wireless Modules: LX5514M

Microsemi's LX5514M power amplifier supports IEEE 802.11b/g/n WLAN applications in the 2.4-2.5GHz frequency range. It joins the company's recently introduced LX5553 and LX5543 front-end modules (FEM) to continue its expansion into the fast-growing market for WLAN products used in space-constrained smartphones and other data-enabled cellular handset designs. The device is based on the company's proven LX5514 PA, which has been streamlined to fit into a compact, ultra-low-profile package. Like the LX5514, the LX5514M includes fully matched input, simplified output matching, an integrated power detect function that not only saves board space but also reduces total BOM cost.
