ADA-4643-BLKG

ADA-4643 Silicon Bipolar Darlington Amplifier Data Sheet Description Features Avago Technologies’ ADA-4643 is an economical, easy-touse, 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.  Small Signal gain amplifier  Operating frequency DC – 2.5 GHz  Unconditionally stable  50 Ohms input & output  Flat, Broadband Frequency Response up to 1 GHz  Operating Current: 20 to 60 mA  Industry standard SOT-343 package  Lead-free option available 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 simultaneous high fT and high NPN breakdown (25 GHz fT at 6 V BVCEO). The process utilizes industry standard device oxide isolation technologies and submicron aluminum multilayer interconnect to achieve superior performance, high uniformity, and proven reliability.
