ADA-4543

Silicon Bipolar Darlington Ampliﬁer

Data Sheet

Description

Features

• Small Signal gain amplifier

Avago Technologies’ADA-4543 is an economical, easy-to-

use, general purpose silicon bipolar RFIC gain block am-

pliﬁers 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.

• Operating frequency DC – 2.5 GHz

• Unconditionally stable

• 50 Ohms input & output

• Flat, Broadband Frequency Response up to 1 GHz

• Operating Current: 10 to 30 mA

• Industry standard SOT-343 package

• Lead-free option available

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 ampliﬁcation.

ADA-4543 is fabricated using Avago’s HP25 silicon bi-

polar process, which employs a double-diﬀused 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.
