Product Description
The SE2595L 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 SE2595L 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 SE2595L 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.
Features
1 Transmit and 1 receive path architecture for
use as MIMO building block.
