SE2568U
2.4 GHz High Efficiency Wireless LAN PA
Preliminary
Applications
IEEE802.11b DSSS WLAN
IEEE802.11g OFDM WLAN
Embedded, SiP modules
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.
