Agilent ADA-4543  
Silicon Bipolar Darlington Amplifier  
Data Sheet  
Features  
• Small Signal gain amplifier  
• Operating frequency DC – 2.5 GHz  
• Unconditionally stable  
• 50 Ohms input & output  
Description  
Surface Mount Package  
SOT-343  
Agilent Technologies’ ADA-4543  
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.  
• Flat, Broadband Frequency  
Response up to 1 GHz  
• Operating Current: 10 to 30 mA  
• Industry standard SOT-343 package  
• Lead-free option available  
Pin Connections and  
Package Marking  
Specifications  
900 MHz, 3.4V, 15 mA (typ.)  
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  
• 15.1 dB associated gain  
• 1.9 dBm P1dB

• 3.7 dB noise figure  
Note:  
• VSWR < 2 throughput operating

and identification.  
ADA-4543 is fabricated using  
Agilent’s HP25 silicon bipolar  
process, which employs a double-  
diffused single polysilicon

“x” = Date code character  
identifies month of manufacture.  
• Single supply, typical Id = 15 mA  
Applications  
• Cellular/PCS/WLL base stations  
process with self-aligned  
submicron emitter geometry. The  
process is capable of simulta-  
neous 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  
interconnect to achieve superior  
performance, high uniformity,  
and proven reliability.
