Description
The SE2595L is a complete 802.11n WLAN RF frontend
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.
