SE2568L: 2.4 GHz High Efficiency Wireless LAN PA
Applications
IEEE802.11b DSSS WLAN
IEEE802.11g OFDM WLAN
Embedded, SiP modules
Product Description
The SE2568L 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 0.9mm
form factor.
The SE2568L is designed for ease of use, with all the
critical input and output matching integrated. The
SE2568L 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.
Features
Dual Mode IEEE802.11b & IEEE802.11g
Integrated PA, digital bias control, 50Ω input and
output match, 3.2GHz TX Filter.
Integrated harmonic filter.
Integrated load insensitive Power Detector, with
<1dB error at 2:1 mismatch
20 dBm Output Power, 802.11b, 11 Mbps, ACPR
