SE2521A60
2.4 GHz Wireless LAN Front End

The SE2521A60 is a complete 802.11 b/g WLAN RF front-end module providing all the functionality of the power amplifier, power detector, T/R switch, diversity switch and associated matching. The SE2521A60 provides a complete 2.4 GHz WLAN RF solution from the output of the transceiver to the antennas 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 SE2521A60 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 1 μsec typical.

The device also provides a notch filter from 3.2-3.3 GHz prior to the input of the power amplifier.

The SE2521A60 is footprint compatible to SiGe’s SE2521A34 and can be placed directly into existing SE2521A34 designs easily providing higher output power solutions.

Please note: SE2521A60-R is being discontinued and is not recommended for new design.
