DATA SHEET SE2568U: 2.4 GHz High Efficiency Wireless LAN PA Applications Description The SE2568U is a complete 802.11 b/g WLAN discrete power IEEE802.11b DSSS WLAN amplifier. The device provides all the functionality of the power IEEE802.11g/n OFDM WLAN amplifier, power detector, filter, associated input, inter-stage and General applications 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 Features input and output matching integrated. The SE2568U includes a Dual mode IEEE802.11b & IEEE802.11g transmitter power detector with 20 dB of dynamic range and a digital Enable for power on/off control. Harmonic filters and an Integrated PA, digital bias control, 50 input and output match, input 3.2 GHz LO rejection filter are integrated on-chip. The power 3.2 GHz TX filter ramp rise/fall time is 0.7 s typical. Integrated harmonic filter The device package and pinout for the 8-pin QFN are shown in Integrated load insensitive power detector, with < 1 dB error at Figure 1.

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.
