ADA-4743
Silicon Bipolar Darlington Amplifier
Data Sheet
Description
Avago Technologies’ ADA-4743 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 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 Avago’s HP25 silicon
bipolar process, which employs a double-diffused
single polysilicon process with self-aligned submicron
emitter geometr y. 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.
