Agilent ADA-4643

Silicon Bipolar Darlington Amplifier

Data Sheet

Features

• Small Signal gain amplifier

• Operating frequency DC – 2.5 GHz

• Unconditionally stable

Surface Mount Package

Description

• 50 Ohms input & output

Agilent 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.

SOT-343

• Flat, Broadband Frequency

Response up to 1 GHz

• Operating Current: 20 to 60 mA

• Industry standard SOT-343 package

• Lead-free option available

Specifications

900 MHz, 3.5V, 35 mA (typ.)

Pin Connections and

Package Marking

The Darlington feedback struc-

ture provides inherent broad

bandwidth performance, result-

ing in useful operating frequency

up to 2.5 GHz. This is an ideal

device for small-signal gain

• 17 dB associated gain

• Single supply, typical I_d= 35 mA

ADA-4643 is fabricated using

Agilent’s HP25 silicon bipolar

process, which employs a double-

diffused single polysilicon

Applications

• Cellular/PCS/WLL base stations

process with self-aligned

• Wireless data/WLAN

• Fiber-optic systems

• ISM

submicron emitter geometry. The

process is capable of simulta-

neous high f_Tand high NPN

breakdown (25 GHz f_Tat 6V

industry standard device oxide

isolation technologies and

submicron aluminum multilayer

interconnect to achieve superior

performance, high uniformity,

and proven reliability.
