Product Description

The SE2521A80 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 SE2521A80

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 SE2521A80 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 SE2521A80 is pin for pin compatible to SiGe’s

SE2521A34 for easy transition of medium power

designs to higher power designs.

The device also provides a notch filter from 3.2-3.3

GHz prior to the input of the power amplifier.
