Description
Hewlett-Packard’s INA-30311 is a
Silicon monolithic amplifier for
applications to 1.0 GHz. Packaged
in a miniature SOT-143 package,
it requires very little board space.
The INA-30311 uses an internally
biased topology which eliminates
the need for external components
and provides decreased sensitivity to ground inductance.
The INA-30311 is designed with
an output impedance that varies
from near 200 Ω at low
frequencies to near 50 Ω at higher
frequencies. This provides a
matching advantage for IF
circuits, as well as improved
power efficiency, making it
suitable for battery powered
designs.

The INA-30311 is fabricated using
HP’s 30 GHz f
Silicon bipolar process which
uses nitride self-alignment submicrometer lithography, trench
isolation, ion implantation, gold
metallization, and polyimide
intermetal dielectric and scratch
protection to achieve superior
performance, uniformity, and
reliability.
