Product Description

The SE2568U is a complete 802.11 b/g WLAN

discrete power amplifier. The device provides all the

functionality of the power amplifier, power detector,

filter, associated input, inter-stage and output

matching in an ultra compact 2mm x 2mm x 0.5mm

form factor.

The SE2568U is designed for ease of use, with all the

critical input and output matching integrated.

The

SE2568U includes a transmitter power detector with

20 dB of dynamic range and a digital Enable for

power on/off control. Harmonic filters and an input

3.2GHz LO rejection filter are integrated on-chip. The

power ramp rise/fall time is 0.7 μs typical.
