Hot-selling and scarce SE2595L Dual-Band 802.11n Wireless LAN Front-End QFN spot stock

Product Descriptions

The SE2595L is a complete 802.11n WLAN RF frontend module providing all the functionality of the  power amplifiers, LNA, power detector, T/R switch,  diplexers and associated matching. The SE2595L provides a complete 2.4 GHz and 5 GHz WLAN Multiple  Input, Multiple Output (MIMO) 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 SE2595L also includes a transmitter power detector for each band with 20 dB of  dynamic range. The power ramp rise/fall time is less  than 0.5 µs.

The device also provides band pass filters for both the  a and b/g bands prior to the input of each 2.4 GHz and  5 GHz power amplifiers, respectively.
