描述 Description

Please note: this product is being discontinued and is not recommended for new designs.

The SE5501L is a complete 802.11n WLAN RF front-endmodule providing all the functionality of the poweramplifiers, LNAs, power detector, Antenna switches,filtering and associated matching. The SE5501Lprovides 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 low noise amplifieras well as a bypass state, for use when high powersignals are being received.

Designed for ease of use, all RF ports are matched to50 Ω to simplify PCB layout and the interface to thetransceiver RFIC. The SE5501L also includes atransmitter power detector for each band with 20 dBof dynamic range.

The SE5501L is optimized for mobile applications withdirect to battery operation.
