Description
M/A-COM’s MA4TD0670 is a high performance silicon bipolar
MMIC housed in a hermetic high reliability package for sur-
face mount usage. The MA4TD0670 is useful where a general
purpose 50Ω gain block with lower (3.0 dB) noise figure is
required. Typical applications include narrow and wide band
IF and RF amplifiers in industrial and military applications.
The MA4TD0670 is fabricated using a 10 GHz f
T
silicon
bipolar technology that features gold metalization and IC
passivation for increased performance and reliability.
