ADA-4643

Silicon Bipolar Darlington Amplifier

Data Sheet

Description

Avago Technologies’ ADA-4643 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-4643 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 f

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.
