3.5 GHz Broadband Silicon
Avago’s ABA-31563 is an economical, easy-to-use,
internally 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 applications, DBS tun-
ers, LNB and other wireless communication systems.
• Operating Frequency DC ~ 3.5GHz
• 21.5 dB Gain
• VSWR < 2.0 throughout operating frequency
• 2.2 dBm Output P1dB
• 13.1 dBm Output IP3
• 3.8 dB Noise Figure
• Unconditionally Stable
• Single 3V Supply (Id = 14 mA)
ABA-31563 is fabricated using Avago’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 fT and high NPN breakdown (25 GHz fT at
6V BVCEO). The process utilizes industry standard
device oxide isolation technologies and submicron alu-
minum multilayer interconnect to achieve superior
performance, high uniformity, and proven reliability.
Surface Mount Package: SOT-363/SC70
• Amplifier for Cellular, Cordless, Special Mobile Radio,
PCS, ISM, Wireless LAN, DBS, TVRO, and TV Tuner
