SE5503A
Dual Band 802.11a/b/g/n Wireless LAN Front End

The SE5503A is a complete 802.11a/b/g/n WLAN RF front-end module providing all the functionality of the power amplifiers, filtering, power detector, T/R switch, diplexers and associated matching. The SE5503A 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 Ω to simplify PCB layout and the interface to the transceiver RFIC. The SE5503A also includes a transmitter power detector with 20 dB of dynamic range for each transmit chain. Each power amplifier has a separate digital enable control for transmitter on/off control. The power ramp rise/fall time is less than 0.7 µsec.

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.

The SE5503A packaged in 4mm x 4mm x 1.0mm, Halogen free, Lead free, ROHS compliant, MSL 3 LGA package.
