SE5501L: Dual-Band 802.11n WLAN/BT Front-End
Applications
IEEE802.11b DSSS WLAN
IEEE802.11a,g,n OFDM WLAN
Embedded applications with Bluetooth (Mobile)
Product Description
The SE5501L is a complete 802.11n WLAN RF front-
end module providing all the functionality of the power
amplifiers, LNAs, power detector, Antenna switches,
filtering and associated matching. The SE5501L
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 low noise amplifier
as well as a bypass state, 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 SE5501L also includes a
transmitter power detector for each band with 20 dB
of dynamic range.
The SE5501L is optimized for mobile applications with
direct to battery operation
