Description
Avago Technologies’ ADA-4543 is an economical, easy-to-
use, general purpose silicon bipolar RFIC gain block am-
pli ers 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 oper-
ating frequency up to 2.5 GHz. This is an ideal device for
small-signal gain cascades or IF ampli cation.
ADA-4543 is fabricated using Avago’s HP25 silicon bi-
polar process, which employs a double-di used 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 inter-
connect to achieve superior performance, high uniformi-
ty, and proven reliability.
