Product Description
The SE2593A20 is a complete 802.11n WLAN RF
front-end module providing all the functionality of the
power amplifiers, LNA, power detector, T/R switch,
diplexers and associated matching. The SE2593A20
provides a complete 2.4 GHz and 5 GHz WLAN
Multiple Input, Multiple Output (MIMO) RF solution
from the output of the transceiver to the antennas in a
compact form factor.
The receive path is designed to maximize
performance by providing both a low noise amplifier
as well as a bypass state, for use when high power
signals are being received.
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 SE2593A20 also includes a
transmitter power detector for each band with 20 dB
of dynamic range. The power ramp rise/fall time is
less than 0.5
μs.
The device also provides band pass filters for both the
a and b/g bands prior to the input of each 2.4 GHz
and 5 GHz power amplifiers, respectively.
The SE2593A20 packaged in 5mm x 6mm x 1.0mm,
Halogen free, Lead free, ROHS compliant, MSL 3
LGA package.
Features
1 Transmit and 1 receive path architecture for
