Description
M/A-COM’s MA4TD0970 is a high performance silicon
bipolar MMIC housed in a hermetic high reliability
stripline package. The MA4TD0970 is designed to use
where a general purpose broad band (4.5 GHz) 50
Ω
gain block is required. Typical applications include nar-
row and wide band IF and RF amplifiers in industrial
and military applications.
The MA4TD0970 is fabricated using a 10 GHz f
T
silicon
bipolar technology that features gold metalization and IC
passivation for increased performance and reliability.
