Product Description
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
