SE2621L
2.4 GHz High Efficiency Wireless LAN Front End

The SE2621L is a complete 802.11b/g/n WLAN RF front-end module providing all the functionality of the power amplifier, power detector, diversity switch and 50 Ω matching on all RF ports. The SE2621L provides a complete 2.4 GHz WLAN RF solution from the output of the transceiver to the antennas in an ultra-compact form factor.

The SE2621L is designed for ease of use, with all the critical matching and harmonic filtering and integrated transmit/receive DPDT switch providing a 50 Ω interface to the antenna.

The SE2621L also includes a transmitter power detector with 20 dB of dynamic range and a digital enable control for transmitter power ramp on/off control. The power ramp rise/fall time is 0.5 μs typical.
