SE2566U
2.4 GHz Dual Channel Wireless LAN Power Amplifier
Preliminary
Applications
IEEE802.11n OFDM WLAN
Access Points, PCMCIA, PC cards
Product Description
The SE2566U is the smallest dual stream 2.5GHz
power amplifier module for 802.11n MIMO
applications.
The module includes two power
amplifier streams, an integrated reference voltage
generator, a separate detector for each stream,
harmonic filters and 3.2GHz notch filters.
The integrated transmit power detector offers 20dB of
dynamic range, and is temperature compensated for
consistent performance from 0 degC to 85 degC. The
integrated reference voltage generator offers digital
enable control, and eliminates the need for analog
bias controls from the baseband while drawing less
than 1uA.
The small 3mm x 3mm footprint of the SE2566U,
together with the integrated 50 ohm match, detector,
harmonic filter and 3.2-3.3 GHz trap filter, result in the
industry’s smallest 2-stream MIMO front end solution
for today’s very small half-minicard form factors.
An integrated receive path is located between the two
transmit paths to offer the designer maximum layout
flexibility in 2x2 or 2x3 architectures.
