Description
Agilent Technologies’ ADA-4643
is an economical, easy-to-use,
general purpose silicon bipolar
RFIC gain block amplifiers
housed in a 4-lead SC-70
(SOT-343) surface mount plastic
package which requires only half
the board space of a SOT-143
package.
The Darlington feedback struc-
ture provides inherent broad
bandwidth performance, result-
ing in useful operating frequency
up to 2.5 GHz. This is an ideal
device for small-signal gain
cascades or IF amplification.
ADA-4643 is fabricated using
Agilent’s HP25 silicon bipolar
process, which employs a double-
diffused single polysilicon
process with self-aligned
submicron emitter geometry. The
process is capable of simulta-
neous high f
T
and high NPN
breakdown (25 GHz f
T
at 6V
BVCEO). The process utilizes
industry standard device oxide
isolation technologies and
submicron aluminum multilayer
interconnect to achieve superior
performance, high uniformity,
and proven reliability.
