Description
The MSA-9970 is a high perfor-
mance silicon bipolar Monolithic
Microwave Integrated Circuit
(MMIC) housed in a hermetic high
reliability package. This MMIC is
designed with high open loop gain
and is intended to be used with
external resistive and reactive
feedback elements to create a
variety of special purpose gain
blocks.
Applications include very broad-
band, minimum ripple amplifiers
with extended low frequency
performance possible through the
use of a high valued external
feedback blocking capacitor;
extremely well matched (–20 dB
return loss) amplifiers; and
negative gain slope amplifiers for
flattening MMIC cascades.
70 mil Package
The MSA-series is fabricated using
HP’s 10 GHz fT, 25␣ GHz f MAX,
silicon bipolar MMIC process
which uses nitride self-alignment,
ion implantation, and gold metalli-
zation to achieve excellent
performance, uniformity and
reliability. The use of an external
bias resistor for temperature and
current stability also allows bias
flexibility.
