Description 
M-Pulse's MP4TD0310 is a high performance silicon 
bipolar MMIC housed in a hermetic high reliability 
package.  The MP4TD0310 is designed for use 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 MP4TD0310 is fabricated using a 10 GHz fT silicon 
bipolar technology that features gold metalization and IC 
passivation for increased performance and reliability.
