Description 
M-Pulse's MP4TD0400 is a high performance silicon 
bipolar MMIC chip.  The MP4TD0400 is designed for 
use where a general purpose 50
 gain block is required.  
Typical applications include narrow and wide band IF 
and RF amplifiers in industrial and military applications. 
The MP4TD0400 is fabricated using a 10 GHz fT silicon 
bipolar technology that features gold metalization and IC 
passivation for increased performance and reliability.
