Agilent ABA-51563
3.5 GHz Broadband Silicon
RFIC Amplifier
Data Sheet
Features
• Operating frequency: DC ~ 3.5 GHz
• 21.5 dB gain
• VSWR < 2.0 throughout operating
frequency
• 1.8 dBm output P1dB
Description
Agilent’s ABA-51563 is an
economical, easy-to-use, inter-
nally 50-ohm matched silicon
monolithic broadband amplifier
that offers excellent gain and flat
broadband response from DC to
3.5 GHz. Packaged in an ultra-
miniature industry-standard
SOT-363 package, it requires half
the board space of a SOT-143
package.
At 2 GHz, the ABA-51563 offers a
small-signal gain of 21.5 dB,
output P1dB of 1.8 dBm and
11.4 dBm output third order
intercept point. It is suitable for
use as buffer amplifiers for
wideband applications. They are
designed for low cost gain blocks
in cellular applications, DBS
tuners, LNB and other wireless
communications systems.
ABA-51563 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.

1. Measurements taken on 50Ω test board shown on Figure 1. Excess circuit losses had been de-embedded from actual measurements. Standard
deviation and typical data based on at least 500 parts sample size from 6 wafer lots. Future wafers allocated to this product may have nominal values
anywhere within the upper and lower spec limits.
