SE5501L

Dual Band 802.11n WLAN/BT Front-End


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

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.
