• 21.5 dB Gain
• VSWR < 2.0 throughout operating
frequency
• 2.2 dBm Output P1dB
Description
Agilent’s ABA-31563 is an
economical, easy-to-use, inter-
nally 50Ω matched, silicon
monolithic broadband amplifier
that offers excellent gain and
broadband response from DC to
3.5 GHz. Packaged in an ultra-
miniature SOT-363 package, it
requires half the board space of
a SOT-143 package.
At 2 GHz, the ABA-31563 offers
a small-signal gain of 21.5 dB,
output P1dB of 2.2 dBm and
13.1 dBm output third order
intercept point. It is suitable for
use as wideband applications.
They are designed for low cost
gain blocks in cellular applica-
tions, DBS tuners, LNB and other
wireless communication systems.
ABA-31563 is fabricated using
Agilent’s HP25 silicon bipolar
process, which employs a double-
diffused single polysilicon
process with self-aligned submi-
cron 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.

deviation and typical data based on at least 500 parts sample size from 2 wafer lots. Future wafers allocated to this product may have nominal values
anywhere within the upper and lower spec limits.
