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 geometry. The process is capable of
simultaneous high f
(25 GHz f
industry standard device oxide isolation technologies
and submicron aluminum multilayer interconnect to
achieve superior performance, high uniformity, and
proven reliability.
