AGILENT ADA-4743

Agilent ADA-4743
Silicon Bipolar Darlington Amplifier
Data Sheet
Features
• Small Signal gain amplifier
The Darlington feedback structure provides inherent broad
bandwidth performance, resulting in useful operating frequency
up to 2.5 GHz. This is an ideal
device for small-signal gain
cascades or IF amplification.
ADA-4743 is fabricated using
Agilent’s HP25 silicon bipolar
process, which employs a doublediffused single polysilicon
process with self-aligned
submicron emitter geometry. The
process is capable of simultaneous high fT and high NPN
breakdown (25 GHz fT 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.
