Product Description
The SE2564L is a complete 802.11bgn WLAN RF
front-end module providing all the functionality of the
power amplifier, power detector, diversity switch and
50 ohm matching on all RF ports. The SE2564L
provides a complete 2.4 GHz WLAN RF solution from
the output of the transceiver to the antennas in an
ultra compact form factor.
The SE2564L is designed for ease of use, with all the
critical matching and harmonic filtering and integrated
transmit/receive DPDT switch providing a 50 Ω
interface to the antenna. The SE2564L 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 0.5 μs typical.
