SE2577L

Dual-Band 802.11n Wireless LAN Front-end Module

The SE2577L is a dual-band passive 802.11n WLAN RF front-end module providing the functionality of spurious filters, switches and diplexer. All RF ports are matched to 50 Ω to simplify PCB layout and the interface to the transceiver RFIC.

The Front End is packaged in a very compact RoHS compliant, Halogen Free, and Lead Free 3mm x 3mm x 0.9mm QFN style package.

Please note: SE2577L-R and SE2577L-RC are being discontinued and are not recommended for new designs.
