SE5511T

Dual Band 802.11n WLAN/BT Front End


The SE5511T is a complete 802.11n WLAN RF frontend module providing all the functionality of the power amplifiers, LNA, power detector, Antenna switches, filtering and associated matching. The SE5511T provides a complete 2.4 GHz and 5 GHz WLAN RF solution from the output of the transceiver to the antennas in a compact form factor.

The receive path is designed to maximize performance by providing both a 5 GHz Low noise amplifier with bypass mode, for use when high power signals are being received.

Designed for ease of use, all RF ports are matched to 50 ! to simplify PCB layout and the interface to the transceiver RFIC. The SE5511T also includes a transmitter power detector for each band with 20 dB of dynamic range.

The SE5511T is optimized for mobile applications with direct to battery operation
