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 2 mm 2 mm 0.5 mm
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 3.2 GHz LO rejection filter are integrated on-chip. The power
ramp rise/fall time is 0.7 s typical.
The device package and pinout for the 8-pin QFN are shown in
Figure 1. A block diagram of the SE2568U is shown in
Figure 2.

Note 1: Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other
parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
CAUTION: Although this device is designed to be as robust as possible, Electrostatic Discharge (ESD) can damage this device. This device
must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body
or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
