Description
M-Pulse's MP4TD0900 is a high performance silicon
bipolar MMIC chip. The MP4TD0900 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 MP4TD0900 is fabricated using a 10 GHz fT silicon
bipolar technology that features gold metalization and IC
passivation for increased performance and reliability.
