描述 Description

The SE5511T is a complete 802.11n WLAN RF frontendmodule providing all the functionality of the poweramplifiers, LNA, power detector, Antenna switches,filtering and associated matching. The SE5511Tprovides a complete 2.4 GHz and 5 GHz WLAN RFsolution from the output of the transceiver to theantennas in a compact form factor.

The receive path is designed to maximizeperformance by providing both a 5 GHz Low noiseamplifier with bypass mode, for use when high powersignals are being received.

Designed for ease of use, all RF ports are matched to50 ! to simplify PCB layout and the interface to thetransceiver RFIC. The SE5511T also includes atransmitter power detector for each band with 20 dBof dynamic range.

The SE5511T is optimized for mobile applicationswith direct to battery operation
