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.
