Dual Band 802.11a/b/g/n Wireless LAN Front End

The SE2547A is a complete 802.11a/b/g/n WLAN RF front-end module providing all the functionality of the power Amplifiers filtering, power detector, Diversity Switch diplexers and associated matching. The SE2547A provides a complete 2.4 GHz and 5 GHz WLAN RF solution from the output of the transceiver to the Antenna in an ultra compact form factor. Designed for ease of use, all RF ports are matched to 50 to simplify PCB layout and the Interface to the transceiver RFIC. The SE2547A also includes a transmitter power detector for each band and transmit chain with 20 dB of dynamic range for each transmit chain. Each transmit chain has a separate digital enable control for transmitter power ramp on/off control. The power ramp rise/fall time is less than 0.7 sec. The device also provides a notch Filter from 3.260- 3.267 GHz and 3.28-3.89 GHz prior to the input of each 2.4 GHz and 5 GHz power Amplifiers respectively. By SiGe Semiconductor
