The SE5511T from Skyworks is a complete 802.11n WLAN RF frontend module that integrates the power amplifiers, LNA, power detector, Antenna switches, filtering and associated matching in to a single compact module. It is a complete 2.4 GHz and 5 GHz WLAN RF solution from the output of the transceiver to the antennas.
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 Ω 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.
