Description 
M-Pulse's MP4TD0370 is a high performance silicon 
bipolar MMIC housed in a hermetic high reliability 
package for surface mount usage.  The MP4TD0370 is 
useful where a general purpose 50
Ω
 gain block is 
required.  Typical applications include narrow and wide 
band IF and RF amplifiers in industrial and military 
applications. 
The MP4TD0370 is fabricated using a 10 GHz fT silicon 
bipolar technology that features gold metalization and IC 
passivation for increased performance and reliability.
