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.
